PURPOSE To compare two rat ovary cryopreservation techniques (vitrification vs. slow freezing) and two postmenopausal stages (early vs. late) with regard to graft take. METHODS Thirty-three Wistar rats were submitted to bilateral oophorectomy. One ovary was submitted to histological analysis while the other was cryopreserved by slow freezing or vitrification. The cryopreserved ovary was thawe...

The objective of this study was to compare utilization of red clover (Trifolium pratense L.) and alfalfa (Medicago sativa L.) by lactating dairy cows. Red clover and alfalfa were harvested and conserved as silage at two maturities in 2 consecutive yr. Each year, diets containing experimental forages and supplemental grain were fed to 16 multiparous Holstein cows in early lactation in a replicat...

OBJECTIVE To evaluate sperm retrieval in men with nonobstructive azoospermia and maturation arrest (MA) undergoing microdissection testicular sperm extraction (micro-TESE). DESIGN Retrospective chart review. SETTING Tertiary referral center. PATIENT(S) Men with nonobstructive azoospermia and MA who underwent micro-TESE. INTERVENTION(S) Microdissection TESE. MAIN OUTCOME MEASURE(S) Spe...

Surgical closure of ventricular septal defect is safe, however, the inherent risks associated with cardiopulmonary bypass and the potential early and late postsurgical complications including complete heart block, arrhythmias, postpericardiotomy syndrome, and rare deaths have led physicians to prefer transcatheter occlusion technique for closure of such defects. The use of Amplatzer muscular ve...

background: respiratory problems are common after long bone fractures. the objective of the present investigation is to evaluate the effect of early fixation of femoral shaft fracture on the incidence of respiratory problems.   methods: the results of early and late stabilization of femoral shaft fractures were studied in 150 patients. the patients were divided into two groups according to the ...

Formation of the Drosophila cellular blastoderm involves both membrane invagination and cytoskeletal regulation. Mutations in src64 and tec29 reveal a novel role for these genes in controlling contraction of the actin-myosin microfilament ring during this process. Although membrane invagination still proceeds in mutant embryos, its depth is not uniform, and basal closure of the cells does not o...

CONTEXT Identification of individuals at high risk of developing psychosis has relied on prodromal symptomatology. Recently, machine learning algorithms have been successfully used for magnetic resonance imaging-based diagnostic classification of neuropsychiatric patient populations. OBJECTIVE To determine whether multivariate neuroanatomical pattern classification facilitates identification ...

The purpose of the present study was to assess clinical outcomes and closure status after the transcatheter closure of patent foramen ovale. Two hundred thirty-seven consecutive patients (mean age 53 +/- 15 years; 48% men) who underwent patent foramen ovale closure for the prevention of recurrent stroke were evaluated. Primary end points were death, recurrent stroke, and residual right-to-left ...

Dermal sinus tracts are formed during the 26th day of gestation from the incomplete closure of cutaneous ectoderm from neural ectoderm.1-5 As remnants of incomplete neural tube closure, they are often associated with dermoid and epidermoid cysts, spinal cord tethering and spinal fluid drainage.1,2,6-8 As such, dermal sinus tracts are diagnosed during early childhood.2,8 These entities most freq...

Right ventricular (RV) pressure overload has a vastly different clinical course in children with idiopathic pulmonary arterial hypertension (iPAH) than in children with pulmonary stenosis (PS). While RV function is well recognized as a key prognostic factor in iPAH, adverse ventricular-ventricular interactions and LV dysfunction are less well characterized and the pathophysiology is incompletel...
