TL;DR: It is suggested that appropriate ecotoxicological risk assessment should make in the areas where Mancozeb is to be use in pest control activities.
Abstract: Mancozeb belong the group of carbamate pesticides in various pest control programs. Ecotoxicological effects of Mancozeb in fishes and other non-targeted organisms not well understood. The present study investigated the effects of Mancozeb and its metabolites ethylenethiourea (ETU) on biochemicals and enzymatic parameters in Clarius batrachus. LC values (LC50) estimate on different life stages of fish that was dose as well as time dependent. The bioassay studied after 24h and 72h during exposure with 80% of 24h of LC50 (22.87mg/l). Protein, amino acids, glycogen, nucleic acids and enzyme succinic dehydrogenase decreased in liver and muscles, but lactic dehydrogenase levels, protease, GOT and GPT increased in the both tissues. Mancozeb is widely used fungicides in fields by the farmers and their surfaces run off goes to the water bodies and affect the life aquatic fauna. On the behalf of present study, it suggested that appropriate ecotoxicological risk assessment should make in the areas where Mancozeb is to be use in pest control activities.

TL;DR: An acidic pectin lyase produced by Aspergillus ficuum MTCC 7591 was purified to apparent homogeneity by ion exchange and gel filtration chromatography and has been found to be very effective in the clarification of sweet lime and orange juices.
Abstract: An acidic pectin lyase (E.C. 4.2.2.10) produced byAspergillus ficuum MTCC 7591 of molecular weight 31.6 kD was purified to apparent homogeneity by ion exchange and gel filtration chromatography. Eighty-six fold purification with 60% yield and a specific activity of 7.8 U/mg protein was obtained. The Km and calculated turnover number (kcat) of the purified enzyme were found to be 0.60 mg/ml and 74 s−1 respectively using citrus pectin as the substrate. The pH and temperature optima were 5.0 and 50°C respectively. Exposed to 24 hours at a particular pH the enzyme was found to be relatively stable in the pH range 2.0–9.0. Exposed to a particular temperature for 1 hour, the enzyme retains full activity up to 40°C. Metal ions and protein inhibitors did not have significant effects on the activity of the enzyme. The enzyme has been found to be very effective in the clarification of sweet lime and orange juices.

TL;DR: Urinary corticoids were markedly elevated in breast cancer patients irrespective of the stage of the disease in comparison with healthy controls and after mastectomy, the values of all three variables declined markedly, approaching usual values with a circadian rhythm resembling the pattern found in clinical health.
Abstract: The circadian periodicity of urinary 17-ketogenic steroids (17-KGS), 17-ketosteroids (17-KS) and creatinine (Cr) was studied preoperatively and on the 9th postoperative day in 25 histopathologically proved breast cancer patients and in 15 healthy Indian women under tropical conditions. A statistically significant rhythm was observed in healthy participants for all three variables. Urinary corticoids were markedly elevated in breast cancer patients irrespective of the stage of the disease in comparison with healthy controls. The degree of elevation was more pronounced preoperatively in advanced stage breast cancer in comparison with other groups. After mastectomy, the values of all three variables declined markedly, approaching usual values with a circadian rhythm resembling the pattern found in clinical health.

TL;DR: Comparison of three methods revealed suitability of manual method based on DNA yield and humic acid content, which could be important for many downstream applications like library preparations during metageomics approach.
Abstract: The isolation of good quality metagenomic DNA from diverse soil, in appreciable amount, is a prerequisite for metagenomics. The availability of commercial kits for isolation of genomic DNAs from soil has drastically expedited the application of metagenomics approach for identifying novel sources of industrially important enzymes. The quantitative and qualitative assessment of metagenomic DNA isolated using either the manual method or the kit-based method should be performed prior to its use in downstream applications. The metagenomic DNA isolated from six different soil samples, using three methods, were analyzed in terms of yield, quality and downstream application as template for PCR amplification. The yield of DNA was approximately 3.52, 7.35, and 232.42 μg of DNA per gram of soil sample for the kit-based method, kit-modified method, and manual method, respectively. The manual method seems to be promising based on better yield and lesser humic acid content than the other two methods. The maximum yield was obtained in the soil collected from teak forest with all the three methods, indicating maximum microbial content and diversity. Furthermore, in terms of its suitability as template DNA for PCR amplification using 16S RNA primer, all methods are equally well. Thus, comparative assessment of three methods revealed suitability of manual method based on DNA yield and humic acid content, which could be important for many downstream applications like library preparations during metageomics approach.
