Stationary cycling is typically recommended following total knee arthroplasty (TKA) operations. However, knee joint biomechanics during cycling remains mostly unknown for TKA patients. Biomechanical differences between the replaced and non-replaced limb may inform applications of cycling in TKA rehabilitation. The purpose of this study was to examine the knee joint biomechanics of TKA patients during stationary cycling. Fifteen TKA participants cycled at 80 revolutions per minute and workrates of 80 W and 100 W while kinematics (240 Hz) and pedal reaction forces using a pair of instrumented pedals (1200 Hz) were collected. A 2x2 (limb × workrate) repeated measures ANOVA was run with an alpha of 0.05. Peak knee extension moment (KEM, p = 0.034) and vertical pedal reaction force (p = 0.038) were significantly reduced in the replaced limbs compared to non-replaced limbs by 21.3% and 5.3%, respectively. Peak KEM did not change for TKA patients with the increased workrate (p = 0.750). However, both peak hip extension moment (p = 0.009) and ankle plantarflexion moment (p = 0.017) increased due to increased workrate. Patients following TKA showed similar decreases in peak KEM and vertical pedal reaction force in their replaced compared to non-replaced limbs, as previously seen in gait. LY3023414 Patients of TKA may rely on their hip and ankle extensors to increases in workrate. Increasing intensity by 20 W did not exacerbate any inter-limb differences for peak KEM and vertical PRF.
The vitamin K epoxide reductase complex subunit 1 (VKORC1) plays an important role in bone development and bone metabolism by influencing the vitamin K cycle. The aim of this study was to investigate the association between VKORC1 gene polymorphisms and bone mineral density and the risk of osteoporosis.

We determined VKORC1 gene polymorphisms (rs9923231 and rs9934488) by using polymerase chain reaction-restriction and Sanger sequencing method in 606 postmenopausal women including 288 osteoporosis patients and 318 healthy controls.

No significant differences were observed in the rs9934488 polymorphisms between the osteoporosis group and controls. Subgroup analyses also indicated no positive result. VKORC1 rs9923231 polymorphism increased the risk of osteoporosis in the homozygous and allelic models. A significant correlation was observed in a subgroup of the elderly (age ≥55years). Additionally, the genotypes of the rs9923231 polymorphism were significantly associated with low body mass index, and T-score, but not with age, serum calcium, or phosphorus.

In conclusion, VKORC1 rs9923231 polymorphism is a genetic contributor to osteoporosis risk and it should be confirmed in large well-designed studies.

While heavy metal toxicity in reefs has been well characterized, information on corals recovery from acute contamination is lacking. We studied for 42 days the ability of the coral Stylophora pistillata from the Gulf of Aqaba (northern Red Sea) to recover from a short (3 days) and prolonged (14 days) copper (Cu) contamination (1 μg L-1), after 11 ('Exp3/D11') and 28 ('Exp14/D28') days of depuration, respectively. Cu caused a decrease in chlorophyll content after 3 days, and in net photosynthesis (Pn) after 14 and 42 days. 'Exp14/D28' showed successful recovery based on Pn and relative electron transport rate, as opposed to 'Exp3/D11'. Results suggest the depuration time may be of greater importance than the exposure period to recover from such contamination.Phosphatidylserine (PS) is an anionic phospholipid that is usually localized in the inner leaflets of the plasma membrane. However, the enzyme scramblase catalyzes the externalization of PS on the outer leaflet of the plasma membrane during apoptosis or cellular stress. This event prompts the recognition of PS displaying cells by phagocytes leading to "apoptotic clearance." Multiple PS receptors (PSRs) mediate this process including members from the TAM (Tyro3, Axl, Mertk) receptor Tyrosine kinases (RTKs) by interacting with PS via bridging proteins like Gas6 and ProS1. Ironically, this network (PS/TAM) that evolved for boosting cellular health through clearance of apoptotic and necrotic cells, has been manoeuvred by pathogens and tumor cells using "apoptotic mimicry." Enveloped viruses, responsible for most of the lethal epidemics and pandemics including the current SARS-CoV2 outbreak, have employed apoptotic mimicry to their advantage. In the current chapter, we summarize the existing knowledge regarding the involvement of PS/Gas6, ProS1/TAM in facilitating infectivity in a diverse set of cell lines, animals as well as organoids. This network executes a largely proviral role in facilitating infection as seen with Zika, Ebola, Influenza and Dengue viruses. However, this response varies with strains and the cells infected, and in some cases, this same signaling displays an antiviral function. We also report multiple studies that have used neutralizing antibodies and small molecule inhibitors in successfully reducing viral replication and ameliorating pathogenicity. Knowledge about this unique signaling pathway and measures that can be taken to inhibit it is most valuable now given how enveloped viruses lead to plagues on the entire globe.TAM receptors belong to the family of receptor tyrosine kinases, comprising of Tyro3, Axl and Mertk receptors (TAMs) and are important homeostatic regulators of inflammation in higher eukaryotes. Along with their ligands, Gas6 and ProteinS, TAMs acts as receptors to phosphatidylserine (PtdSer), an anionic phospholipid that becomes externalized on the surface of apoptotic and stressed cells. TAM receptors, specially Mertk, have been well established to play a role in the process of efferocytosis, the engulfment of dying cells. Besides being efferocytic receptors, TAMs are pleiotropic immune modulators as the lack of TAM receptors in various mouse models lead to chronic inflammation and autoimmunity. Owing to their immune modulatory role, the PtdSer-TAM receptor signaling axis has been well characterized as a global immune-suppressive signal, and in cancers, and emerging literature implicates TAM receptors in cancer immunology and anti-tumor therapeutics. In the tumor microenvironment, immune-suppressive signals, such as ones that originate from TAM receptor signaling can be detrimental to anti-tumor therapy.
