Viability of guinea pig () spermatozoa diluted in Tris-buffer extenders stored at 5.00 ˚C.

The cooling procedure markedly diminishes the quality of guinea pig () sperms, primarily because their membranes are highly susceptible to this process. This susceptibility triggers the generation of reactive oxygen species and free radicals, ultimately leading to lipid peroxidation in the sperm membrane. Surprisingly, there has been a lack of research on the use of Tris-based extenders to safeguard guinea pig sperm under refrigeration conditions.

Assessment of Pedicle screw-Rod implantation as an external fixation method for tibial osteotomy in a canine model.

Recent advancements in minimally invasive osteosynthesis have improved atraumatic techniques for bone fracture fixation. Pedicle screws are implants primarily used for the internal fixation of the spine. To our knowledge, no studies have assessed the use of Pedicle screw-Rod for fixing long bone fractures or osteotomies.

Unusual left colon displacement and clockwise torsion in a 10-month-old Arab filly: A case report.

In this case report, we present an unusual clockwise torsion of left colon around mesenteric root in a 10-month-old Arab filly, highlighting the clinical presentation, diagnostic approach and successful surgical intervention. A 10-month-old Arab filly weighing approximately 250 kg was referred with signs of acute abdominal pain. The history revealed anorexia, restlessness and severe abdominal pain that had begun the previous day.

Surgical management of a Salter-Harris type I proximal physeal fracture of the tibia in a foal: a case report.

Background: One of the traumatic fractures occurring in the hindlimb of the foals is physeal fractures of the tibia. The most common type of proximal tibial fracture in foals is reported to be Salter-Harris type II.

Case Presentation: This case report describes the history, clinical signs, radiographic findings, and surgical management of a proximal physeal fracture of the tibia due to the kick trauma in a 2-weeks-old Kurdish female foal, with signs of left pelvic limb lameness, valgus deviation with non-weight-bearing, non-mobility in stifle region and crepitation in the affected area.

Fetal Nasal Bone Status In Iranian Women Undergoing First-Trimester Screening For Trisomy 21: A Review and an Observational Study.

Background: Failed visualization of the fetal nasal bone (NB) by ultrasound at 11 - 14 weeks of gestation is strongly associated with chromosomal abnormalities. Meanwhile, the incidence of the absent fetal NB in normal fetuses in the first trimester in mothers of different ethnic origins differs significantly. It is, therefore, important to assess ethnic variations in the first-trimester visualization of the fetal NB before introducing this marker into routine screening programs for aneuploidy.

Magnetic resonance imaging of Whipple's disease confined to the CNS presenting with multiple intracerebral mass lesions.

We report a patient diagnosed with Whipple's disease (WD) who presented only with neurological symptoms. Neuroimaging (MRI) showed lesions with marked mass effect similar to infiltrative tumors, which were hypersignal on long TR and hyposignal on short TR images, located in several areas of the brain. In serial controls, lesions resolved with gliosis and atrophic changes as well as migration of active infiltrative-like lesions to new areas.

Migration patterns of herniated disc fragments: a study on 1,020 patients with extruded lumbar disc herniation.

Background Context: Herniated disc fragments are known to migrate in various directions within the spinal canal. To date, no comprehensive studies have been undertaken to examine the migration patterns of herniated disc material using a standard nomenclature and classification system.

Purpose: To report migration patterns of extruded lumbar disc fragments.

Bilateral primary breast lymphoma in a teenage girl with multi-organ involvement.

We present 16 years old girl with primary breast lymphoma involving the both breasts simultaneously and co-incidence of central nervous system (CNS) involvement which originated from the breast, in addition to evidence of lymphoma in multi-organ such as skin, mediastinum and some abdominal viscera. Bilaterality has been observed in some series, but reports are few and series are often very small. Radiologic features may be indistinguishable from those of the other breast malignancies, but it can be concluded that primary involvement of the breast with lymphoma should be considered when breast mass or inflammatory changes occur in a patient without any previously diagnosed lymphoma.

Comparison of time to loss of consciousness and maintenance of anesthesia following intraosseous and intravenous administration of propofol in rabbits.

Objective: To compare time to loss of consciousness (LOC) and effective maintenance of anesthesia following intraosseous (IO) and IV administration of propofol in rabbits.

Design: Evaluation study.

Animals: 24 New Zealand White rabbits.

Evaluation of clinical and paraclinical effects of intraosseous vs intravenous administration of propofol on general anesthesia in rabbits.

This prospective study aimed to compare the intraosseous (IO) and intravenous (IV) effects of propofol on selected blood parameters and physiological variables during general anesthesia in rabbits. Thirty New Zealand White rabbits were studied. Six rabbits received IV propofol (group 1) and another 6 rabbits, were injected propofol intraosseously (Group 2) for 30 minutes (experimental groups).
