Effects of Pasturella Multocida B:2 and its immunogens (LPS and OMP) on reproductive hormones in Nili-Ravi Buffaloes

Livestock is a fundamental part of the agriculture industry in Pakistan and contributes more than 11.53% to GDP. Among livestock species, the buffaloes are regarded as the black gold of Pakistan. Being the highest milk producers globally, Nili-Ravi buffaloes are the most famous ones. Buffaloes are affected by many endemic diseases, and "Hemorrhagic septicemia" (HS) is one of them. This study was designed to ascertain the effects of experimental exposure ofP. multocida B:2 (oral) and its immunogens, i.e., LPS (oral and intravenous) and OMP (oral and subcutaneous) on reproductive hormonal profiles in Nili-Ravi buffaloes. Repeated serum samples were collected from the jugular vein of experimental animals for 21 days (0, 02, 04, 08, 12, 16, 20, 24, 36, 48, 72, 120, 168, 216, 264, 360, 456 and 504 hours). Hormonal assays to determine the serum concentrations of Gonadotropin-releasing hormone (GnRH), Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), Estrogen (E2) and progesterone (P4) were performed using (MyBioSource) commercial Elisa kits. The hormonal profile of all treatment groups of the buffalo heifers exhibited significant (P<0.05) variations as compared to the control group (G-1). These results indicate suppression in Nili-Ravi buffaloes' reproductive hormonal profile on exposure to P. multocida B:2 and its immunogens. This influence warrants that exposure to H.S may be a possible reason for delayed puberty and poor reproduction performance in Nili-Ravi buffaloes.

Nivolumab induced hypophysitis in an advanced RCC patient

Introduction: Immune checkpoint inhibitors (ICIs) are being commonly used to treat solid tumours such as renal cell carcinoma. Hypophysitis is an acute or chronic inflammation of the pituitary gland and nivolumab or pembrolizumab induced hypophysitis is markedly lower compared to ipilimumab. Case report: We present a novel case of a patient with mRCC who was diagnosed with nivolumab induced hypophysitis based on clinical suspicion due to his hormonal profile and a range of symptoms that he developed during nivolumab immunotherapy. Management and outcome: He was treated with high dose of hydrocortisone administered intravenously, subsequently changed to the oral route and physiologic dose. Discussion: Nivolumab induced hypophysitis is a rare condition that usually presents with fewer symptoms. High degree of clinical suspicion and a multidisciplinary team required to diagnose and treat such cases.

Processes of Nutrition, Metabolism, Biosynthesis of Milk Components and Vitality of Cows With High and Low-Fat Milk

The trials were performed on 20 multiparous cows of Holstein breed (39.7 &plusmn; 0.75 kg of milk) at the end of the first phase of lactation this different milk fat (4.1-2.8%). The aim of the research was to study the characteristics of nutrition, metabolism and biosynthesis of milk components in highly productive dairy cows with normal and low milk fat levels and the timing of their productive use. Study the characteristics of fermentation of scar formation substrates and their use in energy metabolism and biosynthesis of the milk components. Found that low fat milk is not associated with a lack of formation of acetate in the rumen (6.1 vs. 6.6 mmol/dl in the contents of the rumen, р&gt;0.05) and the non change in the hormonal profile, but depends on the reduction of fatty acids synthesis de novo in mammary gland, regulated by conjugated higher fatty acids. The result is a reduction in the need of cows in the exchange energy (reduction of heat transfer by 6.2 MJ), a shorter service period (109.5 vs.139 days) and the prolongation of their productive use (the number of lactations correlated back with the level of fat in milk (r=-0.68, p&lt;0.05, n=1300).

Physiological Roles of Red Carrot Methanolic Extract and Vitamin E to Abrogate Cadmium-Induced Oxidative Challenge and Apoptosis in Rat Testes: Involvement of the Bax/Bcl-2 Ratio

The precise analysis of the contents of the red carrot is still ambiguous and its role in the maintenance of male fertility needs to be further reconnoitered. Hence, this study targets the physiological impacts of either red carrot methanolic extract (RCME) or vitamin E (Vit. E), co-administrated with cadmium chloride (CdCl2) on rat testes, specifically those concerned with apoptosis and oxidative challenge. Four groups of adult male rats (n = 12) are used; control, CdCl2, CdCl2+Vit. E and CdCl2 + RCME. LC-MS analysis of RCME reveals the presence of 20 different phytochemical compounds. Our data clarify the deleterious effects of CdCl2 on testicular weights, semen quality, serum hormonal profile, oxidative markers and Bax/ Bcl-2 ratio. Histopathological changes in testicular, prostatic and semen vesicle glandular tissues are also observed. Interestingly, our data clearly demonstrate that co-administration of either RCME or Vit. E with CdCl2 significantly succeeded in the modulation (p < 0.05) of all of these negative effects. The most striking is that they were potent enough to modulate the Bax/Bcl-2 ratio as well as having the ability to correct the impaired semen picture, oxidant status and hormonal profile. Thus, RCME and Vit. E could be used as effective prophylactic treatments to protect the male reproductive physiology against CdCl2 insult.

Endocrine-metabolic Adaptations in Dorper Ewes: Comparison Between Single and Twin Pregnancies During Gestation, Delivery, and Postpartum

The present study involved a blood glucose, hormonal profile, and insulin resistance evaluation in sheep from conception until 48 h postpartum. A total of 60 healthy Dorper ewes, raised under semi-intensive management were included in the study. Two experimental groups were applied: G1, single pregnancy (n = 30) and G2, twin pregnancy (n = 30). The experimental time points were immediately after fixed-time artificial insemination; at 30 d, 90 d, 120 d, 130 d, and 140 d of pregnancy; on the delivery day (DD); and at 24 h (PD1) and 48 h (PD2) postpartum. Blood samples were taken to analyse glucose, insulin, glucagon, cortisol, thyroid hormones (T3 and T4) levels. All parameters showed significant differences over the analysed sample times; however, only cortisol showed differences within groups, with the G1 having higher values than the G2 group. The interaction of the groups in the nine sample times showed a significant result (P = 0.001) only for glucagon. The number of foetuses directly interfered with the glucagon profile throughout gestation and insulin concentration postpartum. The glucose, cortisol, insulin, glucagon, and HOMA IR concentrations increased at DD and decreased at PD1 and PD2. T3 and T4 levels increased at DD. Despite the changes found in the endocrine system and metabolism in Dorper ewes throughout pregnancy, the nutritional management ensured a healthy status during pregnancy, delivery, and postpartum.

IVF efficiency in different phenotypes of polycystic ovary syndrome

Polycystic ovary syndrome occupies a leading place in the structure of endocrine infertility. This article presents the endocrine and metabolic features of the polycystic ovary syndrome phenotypes, as well as modern concepts of efficiency and complications of the use of assisted reproductive technologies, depending on the specific phenotype. The issues of polycystic ovary syndrome influence on selecting the method of assisted reproductive technologies, as well as possible complications that occur during in vitro fertilization and the features of the pregnancy course remain unresolved. The individualization of the approach seems to be promising when taking into account the differences in the hormonal profile and the features of metabolic disorders in each polycystic ovary syndrome phenotype. That may allow us to take one more step towards improving the effectiveness of in vitro fertilization and reducing the frequency of complications in patients with polycystic ovary syndrome.

Effects of FSHR and FSHB Variants on Hormonal Profile and Reproductive Outcomes of Infertile Women With Endometriosis

BackgroundSingle nucleotide variants (SNVs) FSHB:c.-211G&gt;T, FSHR:c.919G&gt;A, and FSHR:c.2039G&gt;A were reported to be associated with the variability in FSH and LH levels, and in vitro fertilization (IVF) outcomes. In this study, we aimed to evaluate the effects of FSHB:c.-211G&gt;T, FSHR:c.919G&gt;A, and FSHR:c.2039G&gt;A variants, alone and combined, on the hormonal profile and reproduction outcomes of women with endometriosis.MethodsA cross-sectional study was performed comprising 213 infertile Brazilian women with endometriosis who underwent IVF treatment. Genotyping was performed using TaqMan real-time PCR. Variables were compared according to the genotypes of each variant and genetic models, and the combined effects of the SNVs were evaluated using the multifactorial dimensionality reduction method.ResultsFSHB:c.-211G&gt;T affected LH levels in women with overall endometriosis and minimal/mild disease. FSHR:c.919G&gt;A affected FSH levels in women with overall endometriosis and the number of oocytes retrieved in those with moderate/severe endometriosis. Moreover, the FSHR:c.2039G&gt;A affected FSH levels in women with overall endometriosis, LH levels and total amount of rFSH in those with minimal/mild disease, and number of follicles and number of oocytes retrieved in those with moderate/severe endometriosis. No effect on hormone profile or reproductive outcomes was observed when the genotypes were combined.ConclusionsVariants of the FSHB and FSHR genes separately interfered with the hormonal profiles and IVF outcomes of women with endometriosis.

Effect of moringa leaf meal and season on blood and hormonal profile of the pearl guinea fowl (Numida meleagris)

This study was undertaken to determine the effect of moringa leaf meal and season on blood and hormonal profile of the Pearl Guinea fowl (Numida meleagris) in the Middle belt of Ghana. Thirty-two (32) males and one hundred and twenty-eight (128) female Pearl Guinea fowls aged one-day-old were used for the study. A 3 x 4 factorial experimental design was used for the experiment. Data collected were analyzed using General Linear Model (GLM) procedure of Statistical Analysis System (SAS for Windows, version 7) and means were separated by the probability of difference (PDIFF) procedure of SAS (2008). Mean cell volume was highest (175.39 fl) among Guinea fowls fed with diet containing 12 % moringa leaf meal level. Guinea fowls fed with diet containing 15 % moringa leaf meal had the highest (3.44 x1012/L) red blood cells production. Eosinophil level was highest (3.95 x1012/L) among Guinea fowls fed with diet containing 9 % moringa leaf meal. Birds fed with the moringa diets recorded the highest (P= 0.022) WBC values as compared to the control diet. Triglycerides, high density lipoprotein and low-density lipoprotein levels increased (P<0.05) with increasing levels of dietary moringa leaf meal in the diet. The highest (P= 0.0025) level of progesterone was observed among birds fed with diet containing 12 and 15 % moringa leaf meal inclusion levels. The level of sodium was highest (166.69 nmol/l) among Guinea fowls fed with diet containing 12 % moringa leaf meal. The major and minor rainy seasons recorded the highest (P<0.05) mean cell hemoglobin, red blood cells, albumin and oestrogen levels. Platelets, follicle stimulating hormone, luteinizing hormone, prolactin and chlorine levels were highest (P<0.05) in the dry season while basophil level was highest in the major rainy season. Cholesterol, triglycerides, high density lipoprotein, low density lipoprotein and potassium levels were highest (P<0.05) in the major rainy season. This study concludes that feeding Guinea fowls with moringa leaf meal had positive effect on some haematological, biochemical and hormonal parameters.

A prospective study of clinicoepidemiology, metabolic and hormonal profile of women with hirsutism in Konaseema region of Andhra Pradesh

Background: Hirsutism is defined as presence of excess coarse hairs appear in male pattern in women.There is various aetiology of hirsutism like Idiopathic hirsutism, PCOS, androgen secreting ovarian tumours, menopause, CAH, Cushing’s syndrome, drugs which increases testosterone level, insulin resistance and tumour secreting androgen. We have designed present study with an aim to study the clinicoepidemiology, metabolic and hormonal profile of women with hirsutism in Konaseema region of Andhra Pradesh.Methods: All patients with hirsutism attending gynaecology outpatient department were selected for study based on inclusion and exclusion criteria. After that patient were examined clinically, BMI was calculated for each patient. Patients were clinically evaluated for signs of excess androgen secretion, Cushing syndrome, metabolic syndrome and hyperprolactinemia. Modified Ferriman-Gallwey scoring system was used for evaluating and quantifying hirsutism.Results: The mean Fasting plasma insulin12.42±2.41 (mIU/dl), the mean of HOMA-IR was 3.14±1.18. The mean value of dehydroepiandrosteronesulphate (DHEAS) 355.78±15.41 mcg/dl. There was statistically significant reduction in modified Ferriman-Gallwey scoring in before and after treatment (12.38± 1.55 vs. 9.62±1.6), the p value was 0.00001. The number of patients with menstrual irregularities were reduced from 63.3% to 20% after treatment and this difference is statistically significant (p=0.04).Conclusions: Hirsutism is associated with insulin resistance and DHEAS concentration was high. Modified Ferriman-Gallwey score was significantly reduced and there was significant weight loss and improvement in menstrual irregularities after treatment.
