Combinational Photothermal-Immunotherapy In article number 2206441, Longjiang Zhang, Peng Huang, Zhongqiu Wang, and co-workers load dual-immune inhibitors nanomodulators for combinational photothermal-immunotherapy through regulating abnormal enzymatic metabolism of IDO, blocking PD-L1/PD-1 CD47/SIRPα to reverse immunosuppressive tumor microenvironment, prevent growth re-challenge.

Nonautotrophic CO(2) metabolism in Opuntia echinocarpa roots was studied with techniques of manometry and radiometry. The roots were grown in a one-quarter strength nutrient solution for several days; the distal 2 cm was used for physiological studies. The roots assimilated significant quantities of (14)CO(2) and appeared to show a crassulacean-type acid metabolism with respect to quality and q...

The regulation of Rubisco activity was investigated under high, constant photosynthetic photon flux density during the diurnal phases of Crassulacean acid metabolism in Kalanchoë daigremontiana Hamet et Perr. During phase I, a significant period of nocturnal, C(4)-mediated CO(2) fixation was observed, with the generated malic acid being decarboxylated the following day (phase III). Two periods ...

Following our behavioral studies demonstrating augmentation of imipramine action by concomitant administration of nicotine, we investigated the effects of one or 14 days of treatment (twice daily) with imipramine and nicotine on dopamine metabolism in various brain areas of rat and noradrenaline in the brain stem. In addition, we evaluated the responses of this metabolism to apomorphine challen...

Overflow metabolism refers to the production of seemingly wasteful by-products by cells during growth on glucose even when oxygen is abundant. Two theories have been proposed explain acetate overflow in Escherichia coli – global control central and local pathway but neither accounts for all observations. Here, we develop a kinetic model E. that quantitatively observed behaviours successfully pr...

The article presents the results of experiments to study effect an organomineral supplement containing a soluble complex Fe, Mn, Zn, Cu, Co, Se, and I with amino acid derivatives on some biochemical parameters rabbit blood. It was found that mineral in form chelates did not have negative body rabbits. main indicators protein metabolism characterized normal state rabbits, which drank water, as r...

Peroxisomes perform a range of metabolic functions which require the movement of substrates, co-substrates, cofactors and metabolites across the peroxisomal membrane. In this review, we discuss the evidence for and against specific transport systems involved in peroxisomal metabolism and how these operate to co-ordinate biochemical reactions within the peroxisome with those in other compartment...

We observed dimethyl sulfide and methanthiol production in pure incubations of the methanogen Methanosarcina acetivorans when carbon monoxide (CO) served as the only electron donor. Energy conservation likely uses sodium ion gradients for ATP synthesis. This novel metabolism permits utilization of CO by the methanogen, resulting in quantitative sulfide methylation.

Mature leaves of well-watered Peperomia camptotricha show Crassulacean acid metabolism (CAM). Young leaves show CAM-cycling in which CO(2) uptake occurs during the day concomitant with a marked diurnal fluctuation of organic acids as in CAM. Evidence is presented suggesting that respiration is the source of CO(2) for nocturnal acid synthesis in leaves exhibiting CAM-cycling. Respiratory quotien...

Growth, protein amount, and activity levels of metabolic pathways in Trichodesmium are influenced by environmental changes such as elevated pCO(2) and temperature. This study examines changes in the expression of essential metabolic genes in Trichodesmium grown under a matrix of pCO(2) (400 and 900 µatm) and temperature (25 and 31°C). Using RT-qPCR, we studied 21 genes related to four metabolic...
