Researchers retrospectively reviewed the vitamin D levels of 1,539 patients, including 448 acute hip fracture patients and 1,091 total hip (THR) or total knee replacement (TKR) patients, from December 2010 to December 2011 at a major medical center in southern California.
Patients were categorized based on their vitamin D levels – deficient, insufficient or sufficient – and according to age and sex. The mean vitamin D levels for the hip fracture and the THR and TKR patients were 26.38 ng/mL and 29.92 ng/mL, respectively. More patients in the hip fracture group were deficient or insufficient (65.8 percent versus 54 percent), and patients age 71 years and older were more deficient or insufficient in the hip fracture group than the joint replacement group (66.7 percent versus 47.13 percent).Overall, the majority of patients age 18 and older of both sexes with hip fractures had insufficient levels of vitamin D, and those age 71 or older had significantly lower levels than the control group of THA and TKA patients.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
