Objective: To evaluate the effect of compound branch chain amino acids injection (Aminic) on protein metabolism in patients with radical resection of cardiac carcinoma.
Methods: Eighty patients with radical resection of cardiac carcinoma were randomly divided into two groups:study group (40 cases) with compound branch chain amino acids injection (Aminic), and control group(40 cases) with amino acids(MPR- F). The patients received total parenteral nutrition with equal calorie and nitrogen from 1st-7th days after operation by central or peripheral vein with infusing time over 12 hours per day. The change of body weight was observed. The serum levels of total protein, albumin,pre-albumin,transferring, and fibronectin were measured.
Results: The body weight was decreased in the two groups after operation, while compared with the study group,the body weight was significantly decreased in the control group (P=0.0250). The positive nitrogen balance recovered two days earlier in study group than that in the control group. Decrease of total protein,albumin were more severe in the control group than those in study group (P=0.0446,P=0.0314 respectively). Compared with the control group,the level of Valine was increased (P=0.0073),and the level of Arginine was decreased more obviously in the study group (P= 0.0212).
Conclusion: The compound branch chain amino acids injection (Aminic) is more beneficial for patients with radical resection of cardiac carcinoma to correct negative nitrogen balance,it can also inhibit decomposition of muscles protein,and improve nutritional conditions.

Corner's rules are well known in describing inter-specific scaling relationships for plant organ size-related traits, from species with thick terminal stems, large leaves, and sparsely branched twigs to species with opposite traits; however, the implications of organ size on physiological functions and growth performance of trees remain unclear. Moreover, whether Corner's rules spectra differ between tree species with simple and compound leaves is not known. Here, we measured key twig morphological traits, physiological characteristics, and radial growth rates of 27 simple- and 6 compound-leaved tree species in a common garden in Northeast China.

Alzheimer's is an advanced nervous disorder related to aging. The present study aimed to determine the effect of eight-week aerobic training, along with the consumption of Linalool, Cineole, and β-Bourbonene, on the prevention and improvement of Alzheimer's disease. Mice were randomly assigned to 8 groups: control group, mice induced with Alzheimer's disease treated with β-amyloid (Alzheimer group), Alzheimer's mice treated with bioactive compounds of herbal medicine (Linalool with a concentration of 25 mg/kg, Cineole with a concentration of 100 mg/kg, and β-Bourbonene with a concentration of 10 μg/ml) by gavage for 8 weeks (Alzheimer+Biocompounds group), Alzheimer's mice treated with aerobic exercise with a moderate intensity treadmill for 8 weeks (Alzheimer's+Training group), Alzheimer's mice treated with bioactive compounds of herbal medicine and aerobic exercise for 8 weeks (Alzheimer+Biocompounds+Training group), healthy mice initially treated with bioactive compounds of herbal medication (Linalool with a concentration of 25 mg/kg, Cineol with a concentration of 100 mg/kg, and β-Bourbonene with a concentration of 0.

Alzheimer's disease (AD) is primarily caused by oxidative stress, hyperphosphorylated τ-protein aggregation, and amyloid-β deposition. Changes in dopaminergic and serotoninergic neurotransmitter pathways are linked to certain symptoms of AD. Derivatives of bicyclic and tricyclic cyclohepta[b]thiophene were developed to identify new potential candidates as acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors for the treatment of AD.

Protein hydrolysis targeted chimeras (PROTACs) represent a different therapeutic approach, particularly relevant for overcoming challenges associated with traditional small molecule inhibitors. These challenges include targeting difficult proteins that are often deemed "undruggable" and addressing issues of acquired resistance. PROTACs employ the body's own E3 ubiquitin ligases to induce the degradation of specific proteins of interest (POIs) through the ubiquitin-proteasome pathway.

Polycyclic aromatic compounds and petroleum hydrocarbons (PHs) are hazardous pollutants and seriously threaten the environment and human health. However, native microbial communities can adapt to these toxic pollutants, utilize these compounds as a carbon source, and eventually evolve to degrade these toxic contaminants. With this in mind, we isolated 26 bacterial strains from various environmental soil samples.
