Allograft Anterior Cruciate Ligament Reconstruction in Patients Younger than 25 Years.

Purpose The purpose of this study was to evaluate the outcomes for patients younger than 25 years who had anterior cruciate ligament (ACL) reconstructions with allograft tissue. Methods A total of 52 ACL reconstructions performed with fresh-frozen, nonirradiated tibialis or Achilles allografts in active patients younger than 25 years. Outcome evaluations included the International Knee Documentation Committee (IKDC) objective and subjective forms, KT-1000 arthrometry and Lysholm.

[Is endoscopy necessary to initiate medical treatment in primary-level medical care patients with not investigated dyspepsia?].

Introduction: Approximately 2 to 5% of primary care consultations are patients with dyspepsia. One of the most controversial points among primary-care physicians and gastroenterologists is the diagnostic-therapeutic approach of the uninvestigated dyspeptic patient.

Aims And Methods: Our aim was to investigate prevalence of organic disease and Helicobacter pylori (Hp) status in uninvestigated dyspeptic out-patients at a primary-care level.

Subcellular distribution of phospholipase A2 and ATPases during capacitation and acrosome reaction in guinea pig spermatozoa.

The presence, distribution, and levels of phospholipase A2 and ATPases activities in those structures of the guinea pig spermatozoa that participate in the acrosome reaction were studied, both before and after capacitation, as well as during the acrosome reaction induced in vitro. Spermatozoa were collected from the cauda epididymis and incubated in the absence and presence of 1.15 mmol/L calcium, with and without the addition of 1 mumol/L A23187.

Screening for thermostability and electrophoretic red blood cell sorbitol dehydrogenase (E.C.1.1.1.14) variants.

A screening for both thermostability and electrophoretic red blood cell sorbitol dehydrogenase (RBC-SORD) variants in blood donors was performed. SORD activity in standard conditions (unheated samples) in 274 individuals was 198 +/- 38.6 mIU/g Hb.
