Nghiên cứu này nhằm đánh giá ảnh hưởng của các phương pháp kích thích khác nhau đến hiệu quả sinh sản ốc bươu đồng. Thí nghiệm được bố trí trong bể có thước (1m × 1m 1 m), mật độ 30 cá thể ốc/m2 (tỷ lệ đực:cái bằng nhau) và mực nước ban đầu là 40 cm. Mỗi thức lặp lại 3 lần với như sau: 1) Tăng 50% nước, kết hợp phơi bóng râm 2 giờ (A50-2h); 2) (A50-3h); 3) 4 (A50-4h); 4) Giảm 75% (D75-2h); 5) (...

Parkinson's disease (PD) is characterized by Lewy body and neurite pathology associated with dopamine terminal dysfunction. Clinically, it motor slowing, rigidity, tremor. Postural instability pain are also features. Physical exercise benefits PD patients - possibly promoting neuroplasticity including synaptic regeneration. In a parkinsonian rat model, we test the hypotheses that exercise: (a) ...

Cyanobacterial alkaline phosphatases (APases) play a key role in organophosphate utilization freshwater. Tracking the distribution of APases can provide insights into physiological response phytoplankton to phosphorus nutrition. Extracellular APase PhoX, one three prokaryotic families, is important for utilization. Because existing methods only give information on bulk activity, specific contri...

In the development of pharmacological probes, 2(3H)-benzoxazolones are viewed as privileged scaffolds. The functionalization nitrogen atom at third position 2(3H)-benzoxazolone moiety is importance because electrical properties this can be crucial for biological activity. purpose study was to use in silico techniques examine affinities 3-substituted-2(3H)-benzoxazolone derivatives against caspa...

quinazolinone derivatives are essential units in a wide range of relevant pharmacophores with a broad spectrum of abilities. due to their wide range of pharmacological and therapeutic activities including anticonvulsant, anti-inflammatory, hypolipidemic, anticancer, and anti-ulcer, the synthesis of quinazolinone moieties as a privileged class of fused heterocyclic compounds, have received much ...

T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety of alcohols. Alcohols are oxidized in situ to aldehydes under mild conditions, which undergo a three-component reaction with N,N'-dimethylbarbituric acid and various isocyanides to afford furo[2,3-d]pyrimidine-2,4(1H,3H)-diones in good yields.

quinazolinone backbone is present in a large number of bioactive substances. since remarkable cytotoxic activity is associated with some 4(3h)-quinazolinones, in this study some 4(3h)-quinazolinone were synthesized and screened against hela cells. the synthesis was performed via reaction of anthranilic acid with dicarboxylic anhydrides to produce carboxylic acids derivatives. the products were ...
