Hypoparathyroidism, which is uncommon, can be attributable to congenital defects (a lack of a quantity of of the four parathyroid glands) in addition to by harm following surgical procedure, radiation, autoimmune circumstances, hypomagnesemia, or metabolic alkalosis. This hormone deficiency results in hypocalcemia and a subsequent improve in phosphorus levels. Calcitonin could additionally be administered to shift the calcium from the bloodstream to the bones. Phosphates could also be administered to right phosphorus deficits, which can lower calcium ranges (see the Fluid, Electrolyte, and Acid� Base Homeostasis chapter). Increasing fluid consumption (either oral or intravenous) will enhance renal excretion of calcium. Additionally, magnesium and pH imbalances may need correction (see the Fluid, Electrolyte, and Acid�Base Homeostasis chapter). Disorders of the Adrenal Gland Adrenal gland disorders may affect one or both areas of the adrenal gland. These problems end in a rise or a lower in a number of adrenal hormones. Depending on the hormone affected and the severity of the condition, adrenal gland disorders can have serious penalties. Several etiologies may find yourself in these circumstances, including tumors, congenital defects, drugs. If not promptly handled, pheochromocytoma can result in hypertensive disaster, stroke, kidney disease, psychosis, and seizures. The most common reason for this excess is iatrogenic, resulting from ingestion of glucocorticoid drugs. The tumor excretes epinephrine and norepinephrine and may be life threatening due to the results of those hormones. The tumors can occur at any age, but are more frequent in early to middle maturity. Clinical manifestations mirror the fight-or-flight response and happen in unpredictable attacks that usually last 15 to 20 minutes. Interventions could additionally be necessary to handle particular issues as they develop. She now has dyspnea from walking one-third of a block, as properly as a persistent cough. Physical examination reveals an anxious woman with blood pressure of 134/70 mm Hg, pulse of 116, respiratory rate of 24 breaths per minute, and weight of a hundred ninety kilos. The affected person is started on albuterol (bronchodilator) and a course of prednisone (glucocorticoid) at forty mg/day for three days, then tapering over 2 weeks. On day 3, she calls again to the clinic to report that her blood glucose stage is 358 mg/dL at four:00 p. All of the next actions are important for this patient to learn regarding glucocorticoid therapy, but which is an important Which of the next endocrine conditions is this patient vulnerable to creating Insulin as wanted per routine sliding scale (dosing based on blood glucose levels) B. Increases in hormone doses could also be required throughout times of infections, stress, and trauma. The patient should wear a medical alert bracelet and carry further medicine always. Endocrine problems are sometimes brought on by congenital defects, tumors, or gland damage. These situations differ from innocent to life threatening, and most are managed simply with medicines and surgery. Clinical manifestations of these circumstances mirror the hormones affected and the diploma of deviation.
Physical adjustments within the body half associated to the feeling account for a lot of the other sensation adjustments. Hearing and vision modifications can be probably the most dramatic, but all senses may be affected by aging. Equipment corresponding to glasses and hearing aids or changes in life-style can compensate for most of the sensory growing older changes. Additionally, intolerance to glare as nicely as issue adapting to darkness and brightness could also be skilled, making driving at night time tough. Keeping a red light on in darkened rooms (such because the hallway or bathroom) might make it easier to see than using an everyday night time light as a outcome of it produces less glare than a white gentle bulb. The eye muscle tissue weaken, decreasing the power to rotate the attention fully and limiting the visible area. Nearly all persons 55 years of age or older want glasses at least part of the time. Only 15�20% of aged individuals have imaginative and prescient deficits extreme sufficient to impair driving capacity, and only 5% become unable to learn. The commonest eye drawback related to getting older is problem focusing the eyes, a Ears All of the ear structures thicken and change with aging, affecting balance and hearing. This listening to loss is accelerated in individuals who had been uncovered to excessive noise or smoking once they had been youthful. Some listening to loss is nearly inevitable, however an estimated 30% of all people older than age 65 have vital hearing impairment. Hearing acuity (sharpness) could decline barely beginning at about 50 years of age, possibly brought on by modifications in the auditory nerve. In addition, the mind might have a slight decreased capacity to process or translate sounds into significant data. Impacted cerumen is another cause of impaired listening to and is more widespread with rising age. Sensorineural listening to loss involves injury to the internal ear, auditory nerve, or the brain. This kind of hearing loss might or might not reply to therapy, but listening to aids can enhance perform. Conductive hearing loss happens when a person has problems transmitting sound via the outer and center ear to the internal ear. Surgery or a hearing aid could additionally be useful for Anatomy and Physiology 451 this sort of hearing loss, depending on the precise trigger. Persistent, abnormal ear noise (tinnitus) is another frequent hearing problem, particularly for older adults. Infectious and Inflammatory Sensory Disorders Infectious sensory problems may result from a wide range of causative brokers, typically triggering the inflammatory response. Eyes Eye infections can result from a big selection of pathogenic organisms, often bacteria and viruses. These situations may also be brought on by other events that may trigger the inflammatory process. Regardless of its trigger, conjunctivitis can generate edema, blurry vision, photophobia, and ache. Allergens and irritants usually produce redness, itching, and excessive tearing. Risk factors for developing conjunctivitis include sporting contact lenses in addition to utilizing contaminated makeup or ophthalmic medicines. Bacterial and viral conjunctivitis are highly contagious by way of direct contact, and steps are essential to stop transmission of the an infection. Diagnostic procedures for conjunctivitis concentrate on figuring out the causative agent and embrace a history, bodily examination (including an ophthalmic examination, typically performed by an ophthalmologist), and drainage culture. These strategies may embody ophthalmic or oral antibiotics, antihistamines, corticosteroid agents, and synthetic tears. Additionally, heat moist compresses can soothe the discomfort associated with conjunctivitis. Maternal transmission of sexually transmitted infections to the infants eyes can happen during vaginal delivery. Because those infections can potentially causing blindness, infants are generally handled with ophthalmic antibiotics shortly after start. Clinical manifestations replicate the inflammatory course of and embody extreme pain, erythema, drainage (clear or mucopurulent), extreme tearing, photophobia, and visible disturbances.
Interestingly, the mixture of high acute consumption of alcohol and cigarettes was related to sperm oxidative harm and a decline in semen quality in a latest report examining semen high quality earlier than and after University examination celebrations [42]. As such, alcohol intake ought to be stored to a minimum, ideally under two commonplace drinks per day, and smoking totally averted. Obesity is related to a decline in sperm quality and a rise in sperm oxidative harm, possibly related to an increase in macrophage activation state inside semen [43]. Weight loss by way of diet, train, or bariatric surgical procedure, nevertheless, is understood to enhance sperm quality [44,46]. A metaanalysis of 10 research analyzing the impression of mobile phone use on sperm quality reported that publicity to cellphones was associated with important reduction in sperm motility and viability, but no clear influence on sperm concentration [51]. Over the last three decades multiple different supplements, each with differing doses and kinds of antioxidants, have been studied in both controlled and noncontrolled settings. A full dialogue of the deserves and weaknesses of those research is beyond the scope of this chapter, however is nicely coated in current critiques [54e56]. However, some basic comments in relation to antioxidant dietary supplements to optimize sperm health are nonetheless warranted. For instance, an antioxidant similar to vitamin C has been shown to spare and/or recycle vitamin E, thereby making sense that each of these antioxidants should be included in an ideal synergistic preparation [54]. Table 2 outlines the components and strengths used in a number of the most commonly used antioxidant dietary supplements designed specifically for augmenting male fertility. L-carnitine Typical Daily Dose 200e1000 mg 200e600 mg 100e200 mcg 15e40 mg 1e3 g 600 mg 60e300 mg 4e6 mg 500 mg 1. As a ultimate word of warning, some authors have instructed that the use of oral antioxidants in the setting of male infertility might have the potential for hurt [59]. First, sperm are normally contained postejaculation within seminal plasma, a physiological medium that contains many antioxidants that help shield sperm from oxidative assault. In order to minimize iatrogenic oxidative injury to sperm, the following laboratory approaches have been suggested (Table 3). Other sperm restoration processes similar to electrophoretic separation [66], annexin V magnetic activated cell separation of apoptotic sperm [67], and the utilization of zeta-potential [68] have also been described as superior strategies for isolating viable sperm with less oxidative damage compared to traditional techniques corresponding to density-gradient centrifugation, although none of those later strategies are in widespread clinical use. Addition of antioxidants (catalase, glutathione, N-acetyl cysteine, nutritional vitamins C and E) plus chelating agents like ethylenediaminetetraacetic acid that take away prooxidant transition metals (iron, copper) from sperm processing and tradition media have all been reported to have the potential to scale back sperm oxidative harm (reviewed in 56 and 60). When processing sperm use the minimal amount of centrifugation attainable to get hold of the required number of sperm (lowest g-force, shortest attainable spin times). Prepare sperm with the least potential delay between pattern production and utilization for fertilization (ideally less than 2e4 h). Use cryopreservation media containing antioxidants and keep away from repeat freeze-thawing of sperm. Therefore sperm ought to ideally be processed in labs with indirect lighting (light mirrored off walls), with appropriate tradition buffer systems and temperature control [60]. Furthermore, those men with a historical past of high semen viscosity must be requested to produce their pattern into tradition media, which frequently permits for simpler and extra speedy restoration of high-quality sperm. However, this embryo has lowered live-birth potential and should probably produce significant well being points later in life [4]. It is believed that virtually all oxidative damage to sperm happens after the sperm has left the protecting setting of the Sertoli cells and are being saved within the epididymis [74]. A collaborative method between patient, clinician, and embryologist will give each couple the most effective possibilities of becoming mother and father to a healthy child.

Synthetic surfactant may be administered to overcome any inadequacies in manufacturing. Anatomy and Physiology 123 Bronchiole Smooth muscle 1 Deoxygenated blood is carried from the guts (to the lungs) by the pulmonary arteries and arterioles. One layer makes up the wall of the capillary, and one layer makes up the wall of the alveolus. Oxygenated blood is carried from the lungs (to the heart) by the pulmonary veins and venules. The process of respiratory is largely involuntary and controlled by the medulla oblongata in the mind. This heart is situated in the mind stem, which controls many very important features within the physique. Breathing contains two phases: inspiration (inhalation-moving air in) and expiration (exhalation-moving air out). These impulses cause the diaphragm to contract, lower, and flatten, which pulls air into the lungs. Nerve impulses cause the intercostal muscles to contract, lifting the ribs up and out. Contraction of the diaphragm and intercostal muscles changes the intrapulmonary pressure, causing air to naturally circulate into the lungs. As the lungs fill with air, the diaphragm and intercostal muscle tissue chill out, returning to their earlier place. Elastic fibers in the lungs assist in passive expiration by causing the lungs to recoil. Expiration can be active-that is, created by contracting the chest and stomach muscular tissues. Tidal quantity is the quantity of air concerned in one normal inhalation and exhalation. This volume is calculated by multiplying the tidal volume by the variety of respirations per minute; the common is 6 liters per minute. Inspiratory reserve quantity is the quantity of air past the tidal quantity that could be taken in with the deepest inhalation. Expiratory reserve volume is the quantity of air past tidal volume that can be forcibly exhaled past the traditional passive exhalation. Some air is at all times present in the lungs, and this amount is called residual quantity. Forced expiratory volume in 1 second is compared to compelled very important capability to diagnose pulmonary illness. The medulla controls breathing through nerve cells that generate nerve impulses to the respiratory muscles. When these ranges go up, respiration depth and rate increase to excrete the surplus carbon dioxide, and vice versa. In some disease states, this drive becomes altered, and oxygen ranges drive breathing. Additionally, stretch receptors within the lungs assist in breathing by detecting when the lungs are full. In such a case, the stretch receptors within the lungs send a message to the medulla to stop firing. This impact, which known as the Hering-Breuer reflex, prevents overinflation of the lungs. In addition to regulating oxygen and carbon dioxide levels, the lungs aid in regulating pH by altering breathing fee and depth. The rising and falling of the chest wall by way of the contraction of the intercostal muscles (muscles between the ribs) is proven within the diagram, illustrating the bellows impact. Inspiration is assisted by the diaphragm, which assumes a lower place in the chest.
Exposure of spermatozoa to minimal ranges of exogenous hydrogen peroxide initiates capacitation, and subsequently induces excessive rates of spermeoocyte fusion. Not solely does A23187 increase intracellular Ca2� ranges, it additionally enhances the speed of hydrogen peroxide production and will increase tyrosine phosphorylation [72]. It is broadly accepted that hydrogen peroxide performs a significant function in the process of capacitation whereas superoxide anion serves as a vital molecule for regulating hyperactivation [77,78]. Superoxide anion generated from an established biological inducer of hyperactivation. These results of low dose hydrogen peroxide were corresponding to that of bicarbonate, which is a known activator of soluble adenylyl cyclase in sperm [81]. As sperm capacitation is an oxidative process, it may possibly apparently be induced exogenously utilizing low concentrations of particular oxidants. Besides superoxide anion and hydrogen peroxide, low and managed concentrations of nitric oxide have a major function in sperm function. Nitric oxide produced by human sperm act as an intracellular signaling molecule in the capacitation and acrosome response. Low ranges of nitric oxide induce capacitation in human sperm in vitro via mechanisms involving hydrogen peroxide [82]. Nitric oxide could either (1) immediately react with hydrogen peroxide to generate singlet oxygen or (2) additional oxidize to nitrosonium cation earlier than reacting with hydrogen peroxide to type peroxynitrite anion. The ensuing singlet oxygen or peroxynitrite anion from these reactions could then act on both membrane or mobile lipids/thiol-containing molecules, respectively. The extremely reactive peroxynitrite anion may additionally decompose into nitrogen dioxide and hydroxyl radical [83]. In a later in vitro examine, nitric oxide-releasing compounds were discovered to hasten the capacitation course of in human sperm and stimulate tyrosine phosphorylation of sperm proteins. In a subsequent examine, it was reported that noncapacitating sperm produced low levels of nitric oxide, whereas capacitating sperm had a time-dependent enhance of nitric oxide production. This early phosphorylation of proteins with the arginine-X-X-Ser/Thr motif [87] is required to activate the late phosphorylation of tyrosine proteins, which takes place 2 h after capacitation had initially begun [88]. Tyrosine phosphorylation of the human sperm flagellar proteins is concerned within the acquisition of hyperactive motility [89]. Intracellular calcium signaling is the primary regulator of sperm flagellar beat and thus regulates sperm motility [93]. These channels are pH-activated and progesterone-sensitive in human spermatozoa [95]. Motility in human sperm is regulated by two independent but interlinked Ca2� signaling pathways comprising (1) the activation of CatSper in the flagellum (by alkalinization or progesterone-induced), which increases intracellular calcium ranges, and (2) the mobilization of stored Ca2� on the sperm neck (via Ca2�-induced Ca2� release). Ca2� indicators generated from each these signaling mechanisms regulate completely different behaviors in human sperm: the release of stored Ca2� strongly induces hyperactive motility whereas activation of CatSper enhances penetration into a viscous medium (mimicking the cervical mucus or cumulus matrix) [96]. Albumin-induced elimination of cholesterol is an essential set off for capacitation and hyperactivation [97]. The removal of cholesterol also correlates with an increase in protein phosphorylation [99]. Acrosome Reaction Upon efficiently present process and finishing a collection of biochemical and physiological processes during hyperactivation and capacitation, the spermatozoa is now ready for the next step of acrosome reaction, which happens instantly after capacitation. Since sperm capacitation is a prerequisite for a standard acrosomal reaction and the following fertilization occasion, only capacitated sperm will proceed to this stage. Acrosome reaction is a process of exocytosis involving the fusion of the outer acrosomal membrane with the plasma membrane of the sperm head. At this level, proteolytic enzymes are released (primarily acrosin and hyaluronidase), which then digest the cumulus oophorus and zona pellucida, creating an aperture to facilitate sperm movement throughout these layers. This course of permits the spermatozoa to acquire entry to the oocyte for spermeoocyte fusion to transpire [105]. In one research, hydrogen peroxide was found to simulate the results of A23187 and upregulate tyrosine phosphorylation of proteins. In one other examine, spermatozoa undergoing A23187-induced acrosome reaction have been discovered to produce marked quantities of superoxide anion. Exogenously added superoxide anion was unable to induce acrosome response but altered the lipid membrane by causing the discharge of unesterified fatty acids from membrane phospholipids [107]. This examine demonstrated that low ranges of each hydrogen peroxide and superoxide anion exert a big effect on acrosome response [108]. Similarly, the results of superoxide anion on acrosome response have been reported to be even less pronounced in comparison with hydrogen peroxide [76,112].
Conventional semen evaluation includes the analysis of bodily traits of semen [12] and substantial diagnostic methods. Recent advancements in reproductive sciences based mostly on the omic technologies, namely, transcriptomics, proteomics, and metabolomics, are projected as better evaluators of each prognosis and treatment of male infertility [13]. Transcriptomic evaluation permits the characterization of testis tissue, epididymis, and sperm transcriptome profiles of fertile, infertile, and/or fertile versus infertile males in a variety of model and nonmodel animals [14e21]. Sperm transcriptome provides novel markers for the regulation of spermatogenesis, which comprises expression of multiple genes sequentially and regularly [22,23]. In this article, the primary focus is on differential gene expression profiles of testis, spermatozoa, and epididymides in infertile males studied via transcriptomic approaches. It proceeds with an summary of the strategies, particularly essentially the most preferred ones, used within the transcriptomic evaluation. Microarray Technique Microarray analysis is based on the molecular hybridization between probe and target that is a nucleotide sequence. Microarray technique permits detection of the expression levels of quite a few genes concurrently [36], under sure organic processes, physiological conditions, and/or illness states [12]. This method also provides an opportunity to discover new tools for diagnosis of male infertility [37]. In the hybridization step, probes hooked up to a glass slide are hybridized to the targets which would possibly be labeled fluorescently [35]. Washing process allows the removing of unhybridized molecules from the slide, and transcripts are scanned with a laser [39], and particular software interprets the depth of the fluorescence signal based on the hybridization level of probe and target [35]. Ultimately, microarray evaluation offers expression changes of a quantity of genes and these are interpreted through bioinformatics instruments [12]. Microarray method has a number of limitations in addition to advantages including requirement of a reference transcript for probe construction and limited sequence resolution [30]. This can be additionally accomplished by the oligo-dT priming method, nevertheless it introduces 30 bias [46,47]. Fragmentation could be achieved by enzymes, divalent cations, and alkali options [31,forty four,47]. Sequencing could be done in single-end (one direction) or paired-end (both direction) when transcripts are ready. One-direction sequencing for transcripts quantification is fast and low-cost, while both-direction sequencing provides stable merchandise (alignment and/or assemblies) and is suitable for locating transcript isoforms and gene annotation [30]. These signals have to be reworked into base sequences, and every base within the sequence needs to be managed for high quality via calculation of a high quality rating [49]. Transcriptomics involves the study of all transcripts and supplies information about gene structure and performance for clarifying molecular mechanism of a biological course of [29] and/or illness [37]. Transcriptomic evaluation of testis, epididymis, and spermatozoa in humans, mice, bovines, chickens, cattle, yaks, and stallions in relation to male fertility and/or infertility have been reported [26,57e63]. Transcriptomic studies of male issue infertility in people are summarized in Table 1. Over the last decade, studies investigating the associations between transcriptomics and male issue infertility have elevated in parallel with advances in transcriptomic approaches [14,66e68]. They have reported downregulation in the expression of 300 genes, and of these genes, 10 were found to be related to infertility [69]. The ratios of the normozoospermic and teratozoospermic groups had been 2:1 and three:1, respectively. Thirty-eight genes had been downregulated in males with cryptorchidism in comparability with controls. Gene ontology analysis has revealed differentially expressed genes concerned within the regulation of spermatogenesis. The expression of genes involved in motility and spermatogenesis has decreased nearly 33-fold in oligozoospermic men compared with their normozoospermic controls. Of the whole of 2081 differentially expressed transcripts, some are instructed to be specific to asthenozoospermic patients. While 247 of these transcripts have been downregulated, 656 have been upregulated, and many of them have been expressed by somatic cells of the testis [74].
Clinical manifestations, when present, usually embrace dysphagia, odynaphagia, chest ache (not associated to eating), weight reduction, hematemesis, and halitosis. Surgery is the therapy of selection, but chemotherapy and radiation are also frequently included in management. Incidence and mortality rates of liver cancer within the United States have tripled since 1980. According to the American Cancer Society (2016), liver most cancers is the 10th commonest most cancers in males and the fifth deadliest most cancers in males. Clinical manifestations are similar to those of different liver ailments: � � � � Anorexia Fever Jaundice Nausea and vomiting � Dr. Walker/Science Source Gastric Cancer Gastric cancer happens in a quantity of varieties, but adenocarcinoma (an ulcerative lesion) is the most frequently encountered type. Incidence and mortality rates of gastric cancer within the United States have declined since 1980. Gastric cancer is prevalent in men and Asians and Pacific Islanders, but mortality charges are highest among African American males. Gastric cancer is strongly related to elevated consumption of salted, cured, pickled, preserved (containing nitrates and nitrites), and smoked foods. A low-fiber food regimen and constipation can increase the risk of developing this cancer as a end result of they delay the time over which the intestinal wall is exposed to these substances. Gastric most cancers is asymptomatic in its early stages, which frequently delays its analysis and treatment. Anatomy and Physiology 299 � Abdominal ache (usually within the upper proper quadrant) � Hepatomegaly � Splenomegaly � Portal hypertension � Edema, third spacing (accumulation of fluid in tissue or body cavities), and ascites � Paraneoplastic syndrome (manifestations and ailments that result from cancer) � Diaphoresis � Weight loss Treatment methods differ depending on the primary site and progression of the most cancers. Chemotherapy is used systemically when metastasis is obvious or could additionally be injected immediately into localized tumors. If the tumor is small, a bit of the liver could additionally be surgically removed (a process called a hepatectomy). If the cancer has unfold all through the liver or has triggered vital damage, a liver transplant will be the most appropriate choice if metastasis has not occurred. Several nontraditional cancer therapy procedures are additionally obtainable to deal with liver most cancers. Cryoablation is a procedure that makes use of excessive chilly to destroy cancer cells by injecting liquid nitrogen into the tumor. Pure alcohol can also be injected into the tumor to dry and ultimately kill the most cancers cells. These manifestations may include the following indicators and symptoms: � Upper stomach ache that may radiate to the back (pain worsens as most cancers progresses) � Jaundice � Dark urine and clay-colored stools � Indigestion � Anorexia � Weight loss � Depression � Malnutrition � Hyperglycemia � Increased clotting tendencies No efficient remedy has been developed for pancreatic cancer. Surgical removal of the tumor (called a Whipple procedure) is recommended, however few pancreatic tumors could be surgically eliminated. Chemotherapy and radiation are sometimes used as palliative remedy or together with surgery. Any biliary blockages that develop will require repair through surgical procedure or endoscopy. Colorectal Cancer Colorectal most cancers most often develops from an adenomatous polyp. According to the American Cancer Society (2016), colorectal most cancers is the third most typical and most fatal most cancers in men and women within the United States, although its rates have been declining since 1980. Dietary components which were associated with colorectal most cancers embrace excessive consumption of fats, energy, pink meat, processed meat, and alcohol as nicely as deficient intake of fiber. When current, medical manifestations may embrace the next signs: � Lower abdominal ache and tenderness � Blood within the stool (occult or frank) � Diarrhea, constipation, or different change in bowel habits � Intestinal obstruction Pancreatic Cancer Pancreatic cancer is an aggressive malignancy (most commonly adenocarcinoma) that may shortly unfold to close by buildings. Other danger factors embrace family history, obesity, persistent pancreatitis, long-standing diabetes mellitus, cirrhosis, alcohol abuse, and tobacco use. This dismal prognosis is due largely to the asymptomatic nature of pancreatic cancer and the dearth of a reliable early detection methodology. Preventive Services Task Force (2016) and American Cancer Society (2016) recommend common colorectal screening starting at 50 years of age for both sexes (earlier if risk elements are present). The screening checks and beneficial intervals are identified right here: � A high-sensitivity fecal occult blood test (which checks for hidden blood in three consecutive stool samples) should be administered every year. Colonoscopy can also be used as a diagnostic test when signs are present, and it could be used as a follow-up test when the results of one other colorectal cancer screening test are unclear or abnormal. The affected person may require a colostomy (a colon diversionary process during which the colon is delivered to the belly wall to drain into an externally hooked up pouch) because of the colon resection.

However, the bloodetestis barrier protects testicular spermatozoa from seminal oxidative stress. Reactive nitrogen species are liable for the subtype of oxidative stress generally known as nitrosative stress. Seminal oxidative stress can occur secondary to unknown causes, iatrogenic causes, or known medical situations, or may originate from lifestyle components or environmental toxicants (see Table 1). The lower levels of complete antioxidant capacity found in this inhabitants additional compound this state of oxidative stress [5].
