Endokrine i metaboličke promjene u mliječnih krava tijekom peripartalnog razdoblja uzrokovane dodatkom vitamina E i cinka u prehrani

The objective of this study was to measure the effect of vitamin E (Vit-E) and zinc (Zn) supplements on endocrine and metabolic changes in peripartum cows. Thirty-two crossbred (Holstein Friesian×Tharparkar) cows were selected 60 days before the expected date of calving. The cows were arbitrary allocated into 4 groups (n = 8), namely: the control, T1, T2, and T3. The feeding schedule was similar in all the groups except that in T1, T2, and T3 60 mg Zn/kg DM, 1000 IU Vit-E and 60 mg/kg + 1000 IU Zn + Vit-E were additionally added, respectively, from day 60 pre-calving to day 60 post-calving. Blood samples were taken on days 60, 45, 30, 15, and 7 before and after the expected day of calving and on the day of calving. Before calving, the cows showed a decrease in plasma leptin, insulin, glucose, Vit-E, and Zn levels, and an increase in plasma non-esterified fatty acid level. However, increases in plasma leptin, insulin, glucose, Vit-E, and Zn and a decrease of plasma non-esterified fatty acid were observed after calving. After calving, group T3 had higher (P<0.05) plasma leptin, insulin, and glucose concentrations than all the other groups. Plasma Vit-E levels were higher (P<0.05) in groups T2 and T3; however, the Zn level was higher (P<0.05) in groups T1 and T2. Milk yield was observed to be higher (P<0.05) in T3 than in the control and groups T1 and T2. The reduction in leptin, insulin, glucose, Vit-E, and Zn during peripartum was ameliorated by Vit-E and Zn supplementationCilj ovoga istraživanja bio je izmjeriti učinak vitamina E i cinka (Zn) na endokrine i metaboličke promjene u krava tijekom peripartalnog razdoblja. U istraživanje su uključene 32 krave, križanke (Holstein-Friesian × Tharparkar), 60 dana prije očekivanog teljenja. Krave su nasumce podijeljene u četiri skupine (n = 8): kontrolnu skupinu, T1, T2 i T3. Hranidbeni je protokol bio sličan u svim skupinama, osim što je skupinama T1, T2 i T3 dodano 60 mg Zn/kg suhe tvari, 1000 i. j. vitamina E te 60 mg/kg + 1000 i. j. Zn + vitamin E, pojedinačno, od 60. dana prije teljenja do 60. dana poslije teljenja. Krv je uzeta 60., 45., 30., 15. i 7. dan prije očekivanog teljenja, na dan teljenja te 60., 45., 30., 15. i 7. dan poslije teljenja. Prije teljenja krave su pokazale smanjenje razine leptina, inzulina, glukoze, vitamina E i cinka te povećanje razine neesterificirane masne kiseline u plazmi. Nakon teljenja razine leptina, inzulina, glukoze, vitamina E i cinka porasle su, a razina neesterificirane masne kiseline u plazmi bila je snižena. Nakon teljenja skupina T3 imala je povišene vrijednosti (P<0,01) leptina, inzulina i glukoze u odnosu na ostale skupine. Razina vitamina E u plazmi bila je veća (P<0,01) u skupinama T2 i T3; razina cinka bila je veća u skupinama T1 i T2. U skupini T3 opažena je viša (P<0,01) količina mlijeka u odnosu na kontrolnu skupinu, skupine T1 i T2. Snižavanje razine leptina, inzulina, glukoze, vitamina E i cinka u peripartalnom razdoblju ublaženo je dodacima vitamina E i cinka u prehrani

Clinical bleeding patterns and management of abnormal uterine bleeding in non-pregnant women: a cross-sectional study

Background: Around 10 to 15 percent of women go through instances of unusual bleeding from their uterus at some point during their reproductive years. Additionally, up to one-third of women may come across irregular menstrual cycles. These irregularities often occur during two crucial phases in a woman's life: firstly, at the beginning of menstruation, which is known as menarche, and secondly, during the transition leading up to menopause, referred to as perimenopause. Aim of study was to determine the clinical bleeding patterns in nonpregnant women and its management. Methods: During the study period spanning from November 2021 to December 2022, a cross-sectional study examined non-pregnant females aged 15 to 55 experiencing abnormal vaginal bleeding (AUB) who provided consent. However, certain exclusion criteria were established to ensure that the study's findings remained pertinent to the target population. Females exhibiting vaginal bleeding attributed to pregnancy or pregnancy-related factors were excluded from the study, as were those with vaginal bleeding stemming from vaginitis, cervical benign, premalignant, or malignant conditions, or traumatic causes. Descriptive statistics were employed in the study. Results: Structural causes [PALM] accounts for 71 (61%) of cases whereas non-structural causes of chronic AUB account for 44 (39%) of cases. AUB-L, 45 (39.2%) was the most frequent finding in females with AUB. The second most common causes are AUB-O 23 (20%) followed by AUB-A 14 (12.2%), AUB-C 08(7%), AUB-M 07 (6.1%), AUB-E 06 (5.2%), AUB-P and AUB-I in 05 (4.3%) each and AUB-N 02 (1.7%). Conclusions: Focusing on Abnormal Uterine Bleeding (AUB), it was observed that AUB-L, attributed to leiomyomas, emerged as the most prevalent cause among affected females. Subsequently, AUB-O, arising from ovulatory dysfunction, and aub-a, linked to adenomyosis, ranked as the second and third most common causes, respectively. Among the clinical manifestations of AUB, prolonged bleeding was identified as the most frequent symptom, followed closely by heavy bleeding.

Dandy Walker variant mimicking as cerebral palsy with severe neurological impairment

Dandy Walker Variant (DWV) is a less severe form of the spectrum of Dandy Walker Malformation (DWM). The DWM is a rare congenital intracranial posterior fossa malformation comprising cystic dilatation of the fourth ventricle, complete or partial agenesis of the cerebellar vermis and an enlarged posterior fossa. Clinically it presents with variable degrees of neurological impairment. Definitive diagnosis of DWM or DWV depends on neuroimaging as most of the clinical signs are not conclusive. This child was clinically suspected as spastic quadriplegic cerebral palsy had incidental finding of DWV on neuroimaging. Hence a definitive diagnosis of DWV was made by MRI in this case. Here we discuss the clinical and radiological aspects of this case with DWV without other associated anomalies yet presenting with clinically significant neurological impairment.

Mosquito larvicidal and antimicrobial activities of synthesized silver nanoparticles (AgNP) using mature fruit extract of Cestrum diurnum L.

592-599Silver nanoparticles (AgNP) were prepared using mature fruit extract of Cestrum diurnum L. (family: Solanaceae) as a reducing agent. The stabilized AgNPs were characterized by time-dependent UV–Vis Spectrophotometric analysis. The spherical/oval shape of the nanoparticle was confirmed by Transmission Electron Microscopy analysis with an average particle size of about 50 nm. The crystalline nature of the AgNPs was confirmed in the XRD spectrum by the characteristic Bragg peaks. Fourier Transform Infrared Spectroscopic analysis of AgNPs confirms the presence of several functional groups. AgNPs showed effective larvicidal activities against larval instars of Anopheles stephensi and Culex quinquefasciatus mosquitoes in the laboratory bioassay. Synthesized AgNPs also showed good antibacterial activity against some fish pathogenic and human pathogenic bacteria which is evident from the inhibition zone diameter in the antibacterial bioassay experiment

Amorphous Alloy Membranes Prepared by Melt-Spin methods for Long-Term use in Hydrogen Separation Applications

Amorphous Ni-based alloy membranes show great promise as inexpensive, hydrogenselective membrane materials. In this study, we developed membranes based on nonprecious Ni-Nb-Zr alloys by adjusting the alloying content and using additives. Several studies on crystallization of the amorphous ribbons, in-situ x-ray diffraction, SEM and TEM, hydrogen permeation, hydrogen solubility, hydrogen deuterium exchange, and electrochemical studies were conducted. An important part of the study was to completely eliminate Palladium coatings of the NiNbZr alloys by hydrogen heattreatment. The amorphous alloy (Ni0.6Nb0.4)80Zr20 membrane appears to be the best with high hydrogen permeability and good thermal stability

Green synthesis of 5-methylpyridinium derivatives by C2-functionalization of pyridine-1-oxide derivatives and their antibacterial activity

An innovative green economic route has been developed for one pot multicomponent synthesis of 5-methylpyridinium derivatives by the reaction of 3-methylpyridine-1-oxide, aromatic aldehyde and β-ketoester catalysed by different ionic liquids (ILs), [BMIM][OH], [BMIM][Cl], [BMIM][Ac] in good to excellent yields. A relative study reinforced that [BMIM][OH] is the best IL for this C2-functionsalization reaction. The main highlights of this synthetic protocol are simple work-up, cost effectiveness and environmentally benign processing. The synthesized derivatives have been assessed for possible antibacterial activity against Staphylococcus aureus and Escherichia coli by using the microdilution method. The results of antibacterial activity suggests that compound 4I shows best antibacterial activity and other compounds show good to moderate activity

Hepatitis C Virus (HCV) and its Genetic Diversity in clinical Isolates from Uttarakhand Population

Hepatitis C is major cause of chronic liver disease. It has been recognised as a global health problem because of the progression to cirrhosis and hepatocellular cancer. Quantization and genotyping of HCV RNAs are important to determine the optimal duration of anti-viral therapy and predict likelihood of response. Total 77 samples were tested biochemically, serologically and molecular assay (Roche COBAS TaqMan 48 Real Time PCR). Out of 77 cases 33(42.85%) were with high viral load (&gt;103IU/ ml of HCV RNA) and low viral load (below 103IU/ml) 2 (2.59%) and 42 (54.54%) were target not detected (below 25 IU/ml). Genotype 3 was prevailed with 68.42% out of 35 cases followed by HCV genotype 15.78% in 1, 5.26% in 2 and 6, 2.63% in 1b and 4. In addition, our studies showed that genotype 1, 2, 4 and 6 (mixed genotype was detected in 1 cases with viral load 6.62 × 108IU/ml). Total protein content in serum in all the cases was average except 04 cases that was having low protein content. 02 cases were having low uric acid content that was having high viral load. From all high positive (high viral load) cases which were further diagnosed for their genotyping in which genotype 3 was prevalent following by genotype1, 1b, 2, 4 and &nbsp;6. Study signifies the gene based diagnosis and its clinical relevance for the proper management of the patients. Keywords: Hepatitis, Chronic, Real Time PCR, Hepatocellular Carcinoma, Serolog
