Modeling Diffusive Motion of Ferredoxin and Plastocyanin on the PSI Domain of MIT9313.

Diffusion of mobile charge carriers, such as ferredoxin and plastocyanin, often constitutes a rate-determining step in photosynthetic energy conversion. The diffusion time scales typically exceed that of other primary bioenergetic processes and remain beyond the reach of direct simulation at the molecular level. We characterize the diffusive kinetics of ferredoxin and plastocyanin upon the photosystem I-rich domain of , the most abundant phototroph on Earth by mass.

Antipsychotic-Treated Schizophrenia Patients Develop Inflammatory and Oxidative Responses Independently From Obesity: However, Metabolic Disturbances Arise From Schizophrenia-Related Obesity.

Objective: To define the impact of obesity on inflammatory and oxidative disturbances in antipsychotic-treated schizophrenia patients.

Methods: Several cytokines, inflammatory, metabolic, and oxidative status markers were evaluated in obese (n = 40) and non-obese (n = 40) antipsychotic-treated patients and compared with age-and BMI-matched controls (n = 80).

Results: Schizophrenia patients had higher leptin, TNF-α, adiponectin, visfatin, resistin, P-selectin, NPY, BDNF, CD40-L, MCP-1, and malondialdehyde, and lower IL-6, ghrelin, neopterin, and vitamin E levels compared to their respective controls (p < 0.

Does having a family member with dementia affect health beliefs about changing lifestyle and health behaviour for dementia risk reduction?

Background: Dementia is a worldwide public health concern. Implementing lifestyle changes that target modifiable risk factors is crucial for reducing the risk of dementia. The aim of this study was to investigate the effect of having family members with dementia on individuals' health beliefs and tendencies towards adopting healthier lifestyles and behaviours.

Perspective on Integrative Simulations of Bioenergetic Domains.

Bioenergetic processes in cells, such as photosynthesis or respiration, integrate many time and length scales, which makes the simulation of energy conversion with a mere single level of theory impossible. Just like the myriad of experimental techniques required to examine each level of organization, an array of overlapping computational techniques is necessary to model energy conversion. Here, a perspective is presented on recent efforts for modeling bioenergetic phenomena with a focus on molecular dynamics simulations and its variants as a primary method.

Is Bone Grafting Unnecessary in the Treatment of Cystic Scaphoid Pseudoarthrosis?

Purpose Of The Study: The basic aim of the treatment of cystic nonunion is to provide stable fi xation and mechanical compression to increase union, but there is no consensus on whether to perform bone grafting in the cystic area or not. The aim of this study was to compare the clinical and radiological results of patients with cystic scaphoid non-union who received open grafting, and internal fi xation and those treated with percutaneous fi xation without grafting. MATERIAL AND METHODS A retrospective evaluation was made of patients included those determined radiologically with Slade and Dodds grade IV scaphoid cystic non-union.
