Based on the results, the N fertilizer for early rice growing in the wet season is suggested as 150-200 kg ha
  , and 200-250 kg ha
  for late rice growing in the dry season. The irrigating threshold and irrigation quota for early rice are suggested as lower than 70% and 30-40 mm, respectively, and, for late rice, 70-80% and 40-60 mm.

  The incidence of inflammatory bowel disease (IBD) continues to increase worldwide. Multiple factors, including diet, loss of the intestinal barrier function, and imbalance of the immune system can cause IBD. A balanced diet is important for maintaining a healthy bowel and preventing IBD from occurring. The effects of probiotic Lactobacillus gasseri-fermented Maillard reaction products (MRPs) prepared by reacting whey protein with galactose on anti-inflammation and intestinal homeostasis were investigated in this study, which compared MPRs and probiotics separately.
 
  In an animal colitis model induced by 2% dextran sulfate sodium (DSS), FWG administration alleviated colon length loss and maintained intestinal immune system homeostasis as reflected by down-regulated interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-α output, and metallopeptidase-9, and epithelial barrier balance as reflected by up-regulated occludin, E-cadherin, and zonula occludens-1 production in the colon. Furthermore, the expressione IBD symptoms through the preservation of mucosal immune responses, epithelial junction and homeostasis through the regulated splenic cytokines. © 2021 Society of Chemical Industry.Turmeric (Curcuma longa L.) is a spice utilized widely in India, China, and Southeast Asia as an aromatic stimulant, a food preservative, and coloring material. The commonly used names of turmeric are castor saffron, turmeric, and saffron root. Turmeric is a yellow-orange polyphenolic natural substance derived from C. longa rhizomes. It has been used to treat common inflammatory diseases, tumors, biliary diseases, anorexia, cough, topical wounds, diabetic injuries, liver disorders, rheumatism, and sinusitis. Extensive studies on the biological properties and pharmacological consequences of turmeric extracts have been conducted in recent years. Curcumin, the primary yellow biocomponent of turmeric, has anti-inflammatory, antioxidant, anticarcinogenic, antidiabetic, antibacterial, antiprotozoal, antiviral, antifibrotic, immunomodulatory, and antifungal properties. Defense assessment tests showed that curcumin is tolerated well at high doses, without adverse effects. Thus, curcumin is a highly active biological material with the potential to treat different diseases in modern medicine. This review article focuses on curcumin's biological characteristics. The most popular methods for curcumin encapsulation are also discussed. Several effective techniques and approaches have been proposed for curcuminoid capsulation, including nanocomplexing, gelation, complex coacervation, electrospraying, and solvent-free pH-driven encapsulation. This review also highlights curcumin's chemical properties, allowing the readers to expand their perspectives on its use in the development of functional products with health-promoting properties. © 2021 Society of Chemical Industry.Multiple factors including habitat loss, pollutants, invasive species, and disease have contributed to the global decline of amphibians, and further declines can be expected as a result of climate change. Warming temperatures may allow for range expansion of invasive plants, and because herbicides are the primary method to control invasive plants, chemical use may increase. A laboratory experiment was performed to examine the individual and combined effects of leachates from the invasive plant European buckthorn (Rhamnus cathartica, L.) and a triclopyr herbicide (Renovate® 3; 0.21 mg/L), which is commonly used to manage R. cathartica, on northern leopard frog (Lithobates pipiens, Schreber) tadpoles at 2 temperature regimes (20 and 25 °C). We measured tadpole growth weekly and body and intestine morphology at the conclusion of the experiment after 8 wk. In the presence of R. cathartica leachates, tadpole growth increased at 25 °C, but only during the first 3 to 4 wk of the experiment. From week 5 until the end of the experiment, tadpoles were significantly smaller at 25 °C compared with 20 °C, but had more developed limb buds at the end of the experiment (except in the triclopyr treatment). Triclopyr had minimal effects on tadpole growth at the low dose used in this study. These results encourage further examination of potential effects of global climate changes in combination with other environmental factors that may impact amphibian populations.

Environments vary both naturally and as a result of human activities, and investigations that simultaneously consider how natural and human-induced environmental variation affect diverse trait types grow increasingly important as human activities drive species endangerment. Here, we examined how habitat fragmentation and structural habitat complexity affect disparate trait types in Bahamas mosquitofish Gambusia hubbsi inhabiting tidal creeks. We tested a priori predictions for how these factors might influence exploratory behaviour, stress reactivity and brain anatomy. We examined approximately 350 adult Bahamas mosquitofish from seven tidal-creek populations across Andros Island, The Bahamas that varied in both human-caused fragmentation (three fragmented and four unfragmented) and natural habitat complexity (e.g.  https://www.selleckchem.com/products/AT9283.html  fivefold variation in rock habitat). Populations that had experienced severe human-induced fragmentation, and thus restriction of tidal exchange from the ocean, exhibited greater exploration of a novel environment, stronger physiological stress responses to a mildly stressful event and smaller telencephala (relative to body size).
