subluxation of the proximal interphalangeal joint (pipj or pastern joint) is an uncommon condition that occurs in the forelimb or hindlimb. thoroughbred racehorses rarely show dorsal pastern subluxation (thoroughbred ringbone) secondarily to an injury to the soft tissues supporting the fetlock. a 4-year-old thoroughbred mare was presented with signs of lameness, swelling of the dorsal aspect of...

testing as a general trait of social life has received a great deal of attention by many language teachers and scholars. throughout history, people have been tested to prove their abilities and experiences or to confirm their capacities. many authorities have said that assessment and instruction should be integrated as a single and inseparable activity which seeks to understand development by a...

background: total knee arthroplasty is a complex procedure aiming to relieve pain and improve function. it is critical to select prosthesis that best cover the bone surfaces. ethnicity may affect fitness of the components mainly designed for caucasian populations. this study aimed to evaluate morphometric features of proximal tibia in iranian population.   methods : during 2013, 150 consecutive...

background: the salvage proximal femoral osteotomy is performed in mild or moderate osteoarthritis when the articulating surfaces are normal and relieves the subject’s pain. because the importance of angular mal-alignment of the femur bone at the hip junction accurate pre-op planning based on patient specific anatomy is required to prevent any lower limb misalignment and joint problem pre-opera...

abstract   background: to evaluate proximal junctional segment changes in adolescent idiopathic scoliosis(ais) the posterior spinal fusion and also instrumentation also and finding of probable risk factors, were all considered in this study.   methods: we retrospectively reviewed radiographs of 121 consecutive patients who underwent posterior spinal fusion for ais from t3 or below, with a mean ...

The applicability to the amphibian limb of the rule of distal transformation, which states that tissue from any level can only become more distal, has been tested during intercalary regeneration following various types of shift-level transplantation. Following the grafting of distal blastemas to proximal levels, such that part of the presumptive pattern is missing, complete limbs nevertheless f...

We investigate the benefits of integrating unmanned aerial vehicles (UAVs) with reconfigurable intelligent surface (RIS) elements to passively relay information sampled by Internet Things devices (IoTDs) base station (BS). In order maintain freshness relayed information, an optimization problem objective minimizing expected sum Age-of-Information (AoI) is formulated optimize altitude UAV, commu...

Objective - The aim of this study was to measure the ratio of bone cortex (C) to bone diameter (D), (C/D) in radius/tibia, metacarpus /metatarsus and proximal phalanges in fore and hindlimbs to be used as a diagnostic guide in metabolic and nutritional diseases in Minature Donkey. Design- Experimental study Animals- Eight adult Minature donkeys. Procedures- Lateromedial, dorsopalmar and dors...

Human organic cation transporter 2 (OCT2/SLC22A2), which is specifically expressed in the kidney, plays critical roles in the renal secretion of cationic compounds. Tissue expression and membrane localization of OCT2 are closely related to the tissue distribution, pharmacological effects, and/or adverse effects of its substrate drugs. However, the molecular mechanisms underlying the kidney-spec...

Long-range oxidative damage to DNA was utilized as a probe to delineate the effects of different ion distributions on DNA charge transport. DNA assemblies were constructed, containing a tethered rhodium intercalating photooxidant, spatially separated from two 5'-GG-3' sites of oxidative damage, with either an A6-tract or a mixed DNA sequence intervening between the guanine doublets; the extent ...
