Levodopa-Reduced Mucuna pruriens Seed Extract Shows Neuroprotective Effects against Parkinson's Disease in Murine Microglia and Human Neuroblastoma Cells, Caenorhabditis elegans, and Drosophila melanogaster.

Abstract
Mucuna pruriens (Mucuna) has been prescribed in Ayurveda for various brain ailments including 'kampavata' (tremors) or Parkinson's disease (PD). While Mucuna is a well-known natural source of levodopa (L-dopa), published studies suggest that other bioactive compounds may also be responsible for its anti-PD effects. To investigate this hypothesis, an L-dopa reduced (<0.1%) M. pruriens seeds extract (MPE) was prepared and evaluated for its anti-PD effects in cellular (murine BV-2 microglia and human SH-SY5Y neuroblastoma cells), Caenorhabditis elegans, and Drosophila melanogaster models. In BV-2 cells, MPE (12.5⁻50 μg/mL) reduced hydrogen peroxide-induced cytotoxicity (15.7-18.6%), decreased reactive oxygen species production (29.1-61.6%), and lowered lipopolysaccharide (LPS)-induced nitric oxide species release by 8.9⁻60%. MPE (12.5-50 μg/mL) mitigated SH-SY5Y cell apoptosis by 6.9-40.0% in a non-contact co-culture assay with cell-free supernatants from LPS-treated BV-2 cells. MPE (12.5-50 μg/mL) reduced 6-hydroxydopamine (6-OHDA)-induced cell death of SH-SY5Y cells by 11.85⁻38.5%. Furthermore, MPE (12.5-50 μg/mL) increased median (25%) and maximum survival (47.8%) of C. elegans exposed to the dopaminergic neurotoxin, methyl-4-phenylpyridinium. MPE (40 μg/mL) ameliorated dopaminergic neurotoxin (6-OHDA and rotenone) induced precipitation of innate negative geotaxis behavior of D. melanogaster by 35.3 and 32.8%, respectively. Therefore, MPE contains bioactive compounds, beyond L-dopa, which may impart neuroprotective effects against PD.

Abstract
Livestock are exposed to different climatic extreme events such as high air temperature, humidity, flood, drought, desert, heat wave, feed, fodder and water scarcity etc. which now seems to be very common in the tropical and subtropical climatic conditions. The climate change scenario is assumed to be a major threat to animal production systems under tropical climate. The demand of food or the food security issue compel us to undertake holistic approach to sustainable livestock production system that may be one of the remedies for fulfilling the demand of fast growing population. The objective of this review is to focus on the major effect on dairy production system and different strategies to overcome the adverse effect of heat stress under tropical climatic conditions. The identificationof unique adaptive traits between and within breeds and their propagation seem to be essential in near future in respect of climate change scenario. The management and feeding strategies proved to be beneficial for relieving adverse effects of heat stress for maintaining the productivity of dairy animals. Nevertheless, decision makers, extension services and research institutions have to support and encourage livestock activities to enhance the animal productivity under changed climate scenario.

Changes in some blood parameters, milk composition and yield of buffaloes (Bubalus bubalis) during the transition period. Anim Sci J 2017; 88:2025-2032. [PMID: 28776872 DOI: 10.1111/asj.12872] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Accepted: 06/06/2017] [Indexed: 11/30/2022]
Abstract
In this study changes in hematochemical parameters, milk composition and yield were investigated in buffaloes during the transition period. A total of 93 buffaloes 113.9 ± 8.03 months old and 535 ± 50 kg average body weight were used. Parity was recorded, blood samples were collected from 80 days pre-partum until 70 days post-partum; milk samples were collected from 5 days to 70 days post-partum. On serum samples, the values of non-esterified fatty acids, β-hydroxybutyrate, glucose, cholesterol, triglycerides, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, urea, total proteins were evaluated. On milk, percentage of fat, protein and lactose, along with the somatic cell count (SCC), milk yield and daily milk production (DMP) were assessed. The peripartum period significantly (P ≤ 0.01) influenced all studied parameters with the exception of glucose. Milk fat percentage showed decreasing trend from 10 until 40 days post-partum; DMP significantly (P ≤ 0.01) increased from 1 day post-partum until 40 days post-partum. Milk yield significantly (P ≤ 0.01) decreased in animals over the sixth lactation. Our results confirmed the importance of transit period in buffaloes. Blood parameters and milk composition alterations are crucial to predict the energy balance status of buffaloes in order to improve their management and feed intake during the transition period.
