RESUMO

In postpartum buffaloes, the process of uterine involution and changes in blood metabolic profile has not been studied in relation to development of subclinical endometritis (SCE). In this study, buffaloes (n = 100) approaching calving were identified. Weekly blood samples were collected on the day of calving up to 6 weeks post-calving. The diameter of uterine horns and onset of ovarian cyclicity (corpus luteum) were recorded through ultrasonography. On the basis of polymorphonuclear cell (PMN) cell count in endometrial cytology at days 45-50 postpartum, buffaloes were divided into two groups, viz., with SCE (> 5% PMN; n = 38) and without SCE (≤ 5% PMN; n = 62). Buffaloes with SCE took longer (P < 0.05) time to complete uterine involution and had larger (P < 0.05) uterine horn diameter between 3rd and 6th weeks postpartum and lower prostaglandin F2α metabolite (PGFM) concentration on the day of calving (P < 0.05) and 1 week (P < 0.001) post-calving than without SCE group. Buffaloes with SCE had lower (P < 0.001) concentration of glucose at weeks 2 and 3, higher (P < 0.001) ß-hydroxybutyric acid (BHBA) at week 3, and lower serum albumin concentration throughout the sampling period (P < 0.05 to 0.001) except at 1 week post-calving as compared to without SCE group. The urea concentration was significantly lower (P < 0.05 to 0.001) in buffaloes with SCE from 4 weeks post-calving onwards than without SCE group. The calcium concentration was lower in buffaloes with SCE at weeks 5 (P < 0.001) and 6 (P < 0.05) postpartum, whereas the concentration of magnesium and phosphorus was uniform between the two groups. No significant (P > 0.05) difference in onset of ovarian cyclicity between the 2 groups was observed, whereas buffaloes with SCE had longer (P = 0.001) median days open (141 days) than their counterpart (117 days). The first service conception rate, cumulative pregnancy rate, and pregnancy rate at 150 days postpartum were lower (P < 0.05) in buffaloes with SCE than without SCE group. In summary, higher BHBA and lower serum concentrations of glucose, albumin, urea, and calcium control onset of subclinical endometritis which in turn has negative impact on fertility of buffaloes.

RESUMO

The Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in outbreak of global pandemic, fatal pneumonia in human referred as Coronavirus Disease-2019 (Covid-19). Ayurveda, the age old practice of treating human ailments in India, can be considered against SARS-CoV-2. Attempt was made to provide preliminary evidences for interaction of 35 phytochemicals from two plants (Phyllanthus amarus and Andrographis paniculata used in Ayurveda) with SARS-CoV-2 proteins (open & closed state S protein, 3CLpro, PLpro and RdRp) through in silico docking analysis. The nucleotide analogue remdesivir, being used in treatment of SARS-CoV-2, was used as a positive control. The results revealed that 18 phytochemicals from P. amarus and 14 phytochemicals from A. paniculata shown binding energy affinity/dock score < - 6.0 kcal/mol, which is considered as minimum threshold for any compound to be used for drug development. Phytochemicals used for docking studies in the current study from P. amarus and A. paniculata showed binding affinity up to - 9.10 kcal/mol and - 10.60 kcal/mol, respectively. There was no significant difference in the binding affinities of these compounds with closed and open state S protein. Further, flavonoids (astragalin, kaempferol, quercetin, quercetin-3-O-glucoside and quercetin) and tannins (corilagin, furosin and geraniin) present in P. amarus have shown more binding affinity (up to - 10.60 kcal/mol) than remdesivir (up to - 9.50 kcal/mol). The pharmacokinetic predictions suggest that compounds from the two plants species studied in the current study are found to be non-carcinogenic, water soluble and biologically safe. The phytochemicals present in the extracts of P. amarus and A. paniculata might have synergistic effect with action on multiple target sites of SARS-CoV-2. The information generated here might serve as preliminary evidence for anti SARS-CoV-2 activity of phytochemicals present from P. amarus and A. paniculata and the potential of Ayurveda medicine in combating the virus.

RESUMO

AIM/BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) is one of the most distressing side effects of highly emetogenic chemotherapy regimens. There have been continuous efforts in the direction to control CINV by many investigators. MATERIALS AND METHODS: Randomly selected patients were those receiving highly emetogenic chemotherapy regimen grouped into yoga and standard antiemetic therapy (n = 50) just before receiving chemotherapy and continued for the following days and other group (n = 50) received only the standard antiemetic agent. Both the groups were assessed, followed for acute and delayed onset of chemotherapy-induced and anticipatory nausea and vomiting using radiation therapy oncology group grading for the same. We also assessed the quality of life of the patient using the Functional Assessment of Cancer Therapy-General questionnaire. RESULTS: The median age group of the patients was 51 years with male:female ratio 2:1, The Eastern Cooperative Oncology Group (ECOG) performance status was 0/1 in 38% of the selected population, while ECOG 2 in 62% of the patients. In yoga arm, insignificant reduction in chemotherapy-induced nausea (90% vs. 78%, P = 0.35) and but significant reduction in vomiting (42% vs. 22%, P =0.01) was observed as compared to the standard antiemetics only arm. There was a significant reduction in Grade 2 and 3 nausea (84% vs. 38% P < 0.01) and vomiting (14% vs. 0% P < 0.01). Quality of life is also significantly improved in the yoga arm, especially in the ECOG 2 performance status. CONCLUSIONS: This study concludes that yoga along with standard antiemetic medication should be a part of the management plan for the cancer patients receiving highly emetogenic chemotherapy.

RESUMO

Kisspeptin (Kiss1), neurokinin-B (NKB) and dynorphin (Dyn) neurons regulate the surge and pulsatile centres of gonadotropin releasing hormone (GnRH) in the hypothalamus and are modulated by the ovarian steroids. Accordingly, we studied the temporospatial expression of Kiss1, its receptor and other genes that regulate GnRH in the preoptic area (POA) and arcuate (ARC) regions of hypothalamus at different phases of bubaline estrous cycle. Brain of buffalo (n = 32) was collected immediately after exsanguination and categorized into early luteal (EL), mid luteal (ML), follicular (FL) stages and acyclic (n = 8/group). Total RNA was extracted from the POA and ARC of each stage and real time PCR amplification of Kiss1, Kiss1r, NKB, NKB receptor (NKBR), Dyn, Dyn receptor (OPRK1), GnRH1, ERα, PR, LEPR and GHSR was done using GAPDH as endogenous control and acyclic stage as calibrator group. Further, immunolocalization of Kiss1 and Kiss1r was done on the hypothalamus. In the POA, significant up-regulation of Kiss1 and NKB with a concomitant down-regulation of Dyn transcripts was recorded at FL stage. There was, however, down-regulation of Kiss1 and Kiss1r during the EL perhaps due to the loss of estradiol as a consequence of ovulation. On the other hand, in the ARC, there was a significant up-regulation of Kiss1 and Dyn at FL and ML, while NKB transcript was consistently down-regulated at any stage of estrous cycle. In the POA, expression of ERα was not modulated; however, PR was down-regulated in the EL. In the ARC, the ERα expression was significantly up-regulated in the EL, whereas, PR was moderately expressed irrespective of the stage of estrous cycle. The immunolocalization study revealed the presence of Kiss1 and Kiss1r in the POA and ARC in the cyclic buffalo with relative abundance at FL. The transcriptional profile of the genes suggests that there is estrous cycle stage specific expression of Kiss1, Kiss1r and other GnRH regulating genes in the POA and ARC regions of hypothalamus in the buffalo. Up-regulation of Kiss1r in the POA during ML and ARC during EL indicates the involvement of kisspeptinergic system in the regulation of low LH pulse frequencies during the early and mid luteal phases in the cyclic buffalo.

RESUMO

A 60-day feeding trial was conducted to study the effect of exogenous enzymes (xylanase and phytase) supplementation in the non-fermented and fermented de-oiled rice bran (DORB)-based diet of Labeo rohita. Four test diets (T1-DORB-based diet, T2-fermented DORB-based diet, T3-phytase and xylanase supplemented DORB-based diet, and T4-phytase and xylanase supplemented fermented DORB-based diet) were formulated and fed to the respective groups. Test diets T3 and T4 were supplemented with 0.01% xylanase (16,000 U kg-1) and 0.01% phytase (500 U kg-1) enzymes. One hundred twenty juveniles of L. rohita, with an average weight 5.01 ± 0.02 g, were stocked in 12 uniform size plastic rectangular tanks in triplicate with 10 fishes per tank following a completely randomized design (CRD). Exogenous enzyme supplementation to the T3 group significantly improved the growth performance of L. rohita (p < 0.05). Fermented DORB fed groups registered significantly lower growth irrespective of the supplementation of exogenous enzymes. The carcass composition (except CP %), enzyme activities (except amylase activity), globulin, and A/G ratio did not vary significantly (p > 0.05). Based on the results of the present study, it is concluded that exogenous enzyme supplementation significantly increases the growth of fish fed with DORB-based diet.

RESUMO

Trace minerals feeding had significant effects on sperm production and fertility with better absorption and proper utilization within the body for optimum reproductive function. Several studies have shown that more influenced trace elements in the diets of animals are copper (Cu) and zinc (Zn). Bucks showing deficiency of this mineral might affect the quality of semen production which in turn would affect the fertility. This experiment was thus designed to test the effects of organic Cu and Zn supplementation on antioxidants enzyme activities and sperm functional attributes in fresh semen of bucks. Forty bucks (n = 40, Aged 5 months) were assigned to ten groups of four animals in each group, supplemented (for a period of 8 months) with different levels of organic Zn: 20 mg (T2), 40 mg (T3) and 60 mg (T4), organic Cu: 12.5 mg (T5), 25 mg (T6), 37.5 mg (T7) and combined organic Zn and Cu: 20 + 12.5 mg (T8), 40 + 25 mg (T9), 60 + 37.5 mg (T10), respectively, per kg dry matter and no additional mineral diet (control; T1). One hundred and sixty semen samples were collected through electro-ejaculator and analysed for sperm quantity, quality, acrosome intactness and plasma membrane integrity and correlated with the catalase, superoxide dismutase, glutathione peroxidase and glutathione reductase enzyme activities in seminal plasma. The results indicated organic Cu and zinc supplemented bucks produced more sperm cells, had higher sperm concentrations, maintained higher (p < .01) sperm livability, plasma membrane and acrosome integrities, more motility and velocity. The increased antioxidant enzyme activities, reduced oxidative stress and lowered lipid peroxidation were positively correlated (p < .05) with the sperm functional attributes. In conclusion, organic Cu and Zn supplement to male goats showed protective roles against oxidative damage and maintained better fresh semen characteristics.

RESUMO

Human milk oligosaccharides (HMOs) are structurally diverse unconjugated glycans with a composition unique to each lactating mother. While HMOs have been shown to have an impact on the development of infant gut microbiota, it is not well known if HMOs also already affect milk microbial composition. To address this question, we analysed eleven colostrum samples for HMO content by high-pressure liquid chromatography and microbiota composition by quantitative PCR. Higher total HMO concentration was associated with higher counts of Bifidobacterium spp. (ρ=0.63, P=0.036). A distinctive effect was seen when comparing different HMO groups: positive correlations were observed between sialylated HMOs and Bifidobacterium breve (ρ=0.84, P=0.001), and non-fucosylated/non-sialylated HMOs and Bifidobacterium longum group (ρ=0.65, P=0.030). In addition to associations between HMOs and bifidobacteria, positive correlations were observed between fucosylated HMOs and Akkermansia muciniphila (ρ=0.70, P=0.017), and between fucosylated/sialylated HMOs and Staphylococcus aureus (ρ=0.75, P=0.007). Our results suggest that the characterised HMOs have an effect on specific microbial groups in human milk. Both oligosaccharides and microbes provide a concise inoculum for the compositional development of the infant gut microbiota.

RESUMO

Bacterial lipoproteins and their synthetic analogs are strong immune modulators of the early host responses. In view of the strong adjuvanticity of bacterial lipopeptide mimics bearing lysine residues, a focused library of lipidated dipeptides and tripeptides has been synthesized with a view to understand the pattern of activity vis a vis the site and extent of lipidation. Compounds 4, 5 and 14 stimulate OVA specific IgG titer, neutralization of antibodies (IgG1 and IgG2a), T lymphocyte sub-sets (CD4/CD8) and its production of soluble mediators for Th1 (IFN-γ)/Th2 (IL-4) cytokines and costimulatory molecules (CD80/CD86) which are ideal traits of immune adjuvants. The results support lipidated lysine dipeptides as potent enhancers of humoral and cell mediated immune responses and thus might become promising immune-adjuvants for self adjuvanted vaccines.

RESUMO

A triterpene compound lupeol isolated from petroleum ether extract of leaves of Celastrus paniculatus was screened for wound healing activity (8 mg/ml of 0.2% sodium alginate gel) by excision, incision and dead space wound models on Swiss Albino rats (175-225 g). In lupeol treated groups wound healing activity was more significant (17.83+/-0.48) than the standard skin ointment nitrofurazone (18.33+/-0.42). Epithelialization of the incision wound was faster with a high rate of wound contraction (571.50+/-5.07) as compared with the control group. In dead space wound model also the weight of the granulation tissue of the lupeol treated animal was increased indicating increase of collagenation and absence of monocytes. The comparative docking of isolated lupeol molecule and standard drug nitrofurazone to glycogen synthase kinase 3-beta protein by Wnt signaling pathway also supported the wound healing property of lupeol. The activation domain of GSK3-beta consisted of Tyr216, with residues Asn64, Gly65, Ser66, Phe67, Gly68, Val70, Lys85, Leu132, Val135, Asp181 in the active pocket docked with lupeol at the torsional degree of freedom 0.5 units with Lamarckian genetic algorithm showed the inhibition constant of 1.38 x 10(-7). The inhibition constant of nitrofurazone was only 1.35 x 10(-4).

RESUMO

Green teas were made by inactivating the enzymes present in fresh leaves of coarse/pruned (unused) and normal (used for tea) grades using different sources of thermal energies. Green teas were extracted in a Soxhlet using different solvents. The obtained miscella was subjected to concentration to give the extract. The extract was subjected to solvent-solvent extraction. Solvent extract was concentrated to obtain conserve. The yields of conserves are 17 +/- 0.8 and 15 +/- 0.8% from green teas of normal and coarse tea leaves, respectively. The radical scavenging activity of these extracts was evaluated using a DPPH in vitro model system. The total polyphenol content was also determined and found to be higher in conserves from normal tea leaves. However, radical scavenging activity of conserves from coarse and normal green tea leaves was found to be >90% at 15 ppm concentration. The HPLC profiles of these conserves were used to quantify the total catechin content with the help of calibration curves prepared using authentic samples at known concentrations. The total catechin content is found to be in the range of 55-85%. Results indicated that the extracts from coarse leaves also possess potential biological activity and could be used as nutraceuticals as well as for preservation purposes in food formulations.

RESUMO

Ethanolic extract of H. rhamnoides L. leaf (HL-EOH), water and ethanolic extract of H. rhamnoides fruit (HF-W and HF-EOH), and H. rhamnoides flavone from fruit (HR-flavone) were evaluated against percutaneously administered sulphur mustard (SM), a chemical warfare agent. The animals administered with SM (9.7, 19.3 and 38.7 mg/kg) died at various days depending upon the dose and there was a significant reduction in the body weight. The H. rhamnoides extracts (1 g/kg; 3 doses; po) significantly protected the lethality, with a protective index of 2.4, 1.7, 1.7 and 2.2 for HL-EOH, HF-W, HF-EOH and HR-flavone respectively. Reduced glutathione (GSH) and oxidized glutalthione (GSSG) levels were reduced, and malondialdehyde (MDA) was elevated after percutaneous administration of SM. Oral administration of HL-EOH and HR-flavone significantly protected the body weight loss. Recovery in the levels of GSH, GSSG and MDA were also observed following oral administration of HL-EOH and HR-flavone. All the extracts were non-toxic and the LD50 was more than 5 g/kg. The present study shows that percutaneous administration of SM induces oxidative stress and ethanolic extract of leaf of H. rhamnoides and H. rhamnoides flavone from fruit can significantly protect it.

RESUMO

This study was undertaken to evaluate the efficacy of a homeopathic complex in the management of true anoestrus in crossbred cows. Six anoestrus cows were treated with a homeopathic complex (Calcarea phosphorica 30c, Aletris farinosa 30c, Pulsatilla 30c, Aurum muriaticum natronatum 30c, Sepia 30c and Phosphorus 30c in equal proportion, 15 pills twice daily orally for 10 days). Six animals acted as control without any treatment. Treatment was 100% effective in inducing oestrus in anoestrus cows with mean interval of 27.5+/-5.3 days. All animals conceived and overall conception rate was 54.5% with 1.83 services per conception. In the homeopathic complex treated group, increased serum oestradiol concentration (20.88+/-5.60 to 27.80+/-7.28 pg/ml) was observed compared to the pretreatment (11.71+/-2.06 pg/ml) and control value (10.43+/-1.77 to 13.94+/-3.14 pg/ml). The homeopathic complex medicine may be effective and economical in the treatment of true anoestrus condition in cows.

RESUMO

Biological active compounds such as insulin, heparin, progesterone and labeled-LH were entrapped in glutaraldehyde cross-linked bovine serum albumin (BSA) and human serum albumin (HAS) microspheres. Studies were carried out for their binding capacity and biodegradability using new proteolytic enzymes. Effects of proteolytic enzymes such as trypsin, chymotrypsin, papain and pronase-E on microspheres were studied in order to understand the biodegradability of the cross-linked proteins. It has been observed that labeled-LG was entrapped 60% in BSA and HAS microspheres. Labelled-LH-BSA, Labelled-LH-HAS and insulin microspheres were injected into mice and rabbits. It was observed that these cross-linked microspheres were biodegradable and the process appeared to be slow one, useful for sustained release of hormones. It was also observed that these albumin microspheres exhibit fluorescence at 495 nm.

RESUMO

Ten metals were assayed in 21 Indian ponds which comprised three groups: (i) eutrophic alkaline ponds containing <2.5 mM potassium and thick growths of Microcystis aeruginosa or Microcystis flos-aquae during most of the year, (ii) equally eutrophic alkaline ponds containing >2.8 mM potassium and no detectable Microcystis growth, and (iii) oligo- or mesotrophic ponds with various potassium and hydrogen ion concentrations and no persistent Microcystis blooms. The effects of potassium on Microcystis growth were examined in filter-sterilized pond water and in defined culture media. A 50% reduction in the 10-day yield of cultured M. aeruginosa was observed in DP medium and pond water supplemented with 1 and 3 mM KCl, respectively. In contrast, the addition of 2 to 30 mM NaCl did not suppress the growth of M. aeruginosa in either DP medium or pond water. Both 5 mM KCl and 20 mM KHCO(inf3) in J medium strongly inhibited the growth of M. flos-aquae C3-9, whereas 5 to 30 mM NaCl had no effect and 20 mM NaHCO(inf3) was stimulatory. For pond water cultured with a mixture of M. aeruginosa and the duckweed Wolffia arrhiza, M. aeruginosa dominated in unsupplemented water and W. arrhiza dominated in water supplemented with 4.8 mM KCl. Implications for the ecology and control of Microcystis blooms are discussed.

Two hundred mothers of children under five years of age having lower respiratory tract infection were interviewed with the help of pretested unstructured questionnaire to know the danger signs perceived by her in a child suffering from pneumonia and the home remedies used by them before seeking medical help. 'Pasli Chalna' and refusal to feed were the most common symptoms perceived as dangerous. 'Pasli Chalna' correlated with retractions in 91.9% and fast breathing in 8.1% cases. Honey (25%) and Ginger (27%) were the most common home remedies used for relief of cough. Self advised medications were used by 24% mothers and majority (58.4%) gained this knowledge from mass media.

RESUMO

Twenty-five out of 55 patients of enteric fever were documented as multidrug resistant enteric fever cases. In the resistant cases the drug sensitivity of salmonella species in vitro were mainly augmentin, ceftriaxone, aminoglycosides, ciprofloxacin and norfloxacin. Sixteen patients were treated with ciprofloxacin and 9 were treated with norfloxacin for 14 days. Fever touched normal in 62.5% cases with ciprofloxacin and in 33.3% cases with norfloxacin by the 7th day. It became normal in 88% with ciprofloxacin and in 66% with norfloxacin by the 10th day and it became normal in 100% cases in each group by the 14th day. The newer 4-quinolones can be recommended in multidrug resistant enteric fever in adults.

RESUMO

PIP: Vitamin A deficiency has long been associated with xerophthalmia and night blindness; it has recently been linked to a predisposition to infections and vice versa, which suggests a direct relationship to child mortality. In Asian countries, 5 million children suffer from xerophthalmia and almost 25% become blind. The high mortality associated with keratomalacia was assumed to be due to associated deficiencies. Research today suggests that Vitamin A has a stabilizing effect on lysosomal membranes and augments the immune response; there has been documented non-specific resistance to infection in mice treated with Vitamin A. In clinical studies, Vitamin A deficiency has been linked to increased susceptibility to diarrhea and respiratory tract infections in children. However, other studies have shown mixed results when attempting to link xerophthalmia or Vitamin A deficiency in humans to diarrhea, although strong evidence suggests this to be the case. Based on this research, it can be assumed that Vitamin A supplementation could reduce child mortality in areas where the deficiency is common. Intervention studies have found a reduction in mortality in treatment and control placebo groups, but not in groups which received neither, suggesting that regular contact with health officials was the most important factor. Since Vitamin A treatment is not an instant remedy for reducing childhood mortality, research and practice efforts should focus on promotion of consumption of easily available and inexpensive Vitamin A-rich foods with supplementation reserved for children with symptoms of Vitamin A deficiency. The 1988 World Health Organization guidelines for treatment and prevention of Vitamin A deficiency present the best available treatment dosage and schedule.^ieng

RESUMO

The protein kinase inhibitor staurosporine has been used to design a series of selective bisindolylmaleimide inhibitors of protein kinase C (PKC). Guided by molecular graphics, conformational restriction of the cationic side chain has led to ATP competitive inhibitors of improved potency and selectivity. Two compounds have been further evaluated and were shown to inhibit PKC of human origin and prevent T-cell activation in a human allogeneic mixed lymphocyte reaction. One of these compounds was orally absorbed in mice and antagonized a phorbol ester induced paw edema in a dose-dependent manner. This compound also selectively inhibited the secondary T-cell mediated response in a developing adjuvant arthritis model in rats and provides evidence for the potential use of PKC inhibitors as therapeutic immunomodulators.
