Testic!

PURPOSES: Synchrotron radiation (SR) X-ray has great potential for cancer treatment and medical imaging. It is of significance to investigate the mechanisms underlying the effects of SR X-ray irradiation on biological tissues, and search for the strategies for preventing the damaging effects of SR X-ray irradiation on normal tissues. The major aim of our current study is to test our hypothesis that poly(ADP-ribose) polymerase (PARP) plays a significant role in SR X-ray-induced tissue damage...

Spir proteins are the founding members of the novel class of WH2 domain containing actin nucleation factors. They initiate actin polymerization by binding of actin monomers to four WH2 domains in the central part of the proteins. Despite their ability to nucleate actin polymerization in vitro by themselves, Spir proteins form a regulatory complex with the distinct actin nucleators of the formin subgroup of formins. The mammalian genome encodes two spir genes, spir-1 and spir-2. The corresponding proteins have an identical structural array and share a high degree of homology...

In our report we present a rare case of primary non Hopdgkin lymphoma of the testis in 70-years-old man, who was diagnosed and treated from syderopenic anemia. Here we demonstrate difficulties with differential diagnosis mentioned tumor.

OBJECTIVE: To investigate the distribution characteristics of Y chromosome haplogroups in Sichuan Han population. METHODS: Using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), denatured high performance liquid chromatography (DHPLC) and DNA sequencing methods, 18 Y-chromosome bialletic markers were detected to type Y chromosome haplogroups in 341 unselected men from Sichuan Han population. RESULTS: A total of 14 haplogroups were observed, in which haplogroups H2 and H4 were identified for the first time in Sichuan population, and haplogroups H14 and N* were found firstly in Chinese...

UNLABELLED: The aim of this work was to assess benefits and complications of laparoscopic procedures of varicocoelas in children and adolescents, conducted in our clinic. MATERIAL AND METHODOLOGY: From 2000 to 2004, 202 patients (198 with leftsided, 2 with rightsided and 2 with bilateral varicocoelas) underwent laparoscopic procedures in our clinic. Patients with stage II and III varicocoelas were operated. The median age of the operated patients was 15 years (range 11-18 years)...

A group of 103 patients operated for lung metastases in the Surgical clinic of the FNsP of L. Dérer and in the II Surgical clinic of L. Pasteur is assessed in this work. Minor operations of atypical resection prevailed among the resections. The postoperative mortality in the whole group was 1.9%. The best long-term survival rates were reached in tumors primarily treated by chemotherapy and followed by the lung metastasectomy. All patients in this group suffered from testical tumors and their long-term survival rate was 69%...

The cellular degeneration, present at the criptorchidism leads to a malfunction in the spermatogenosis and it's due to cellular apoptosis (programed cellular death). This process is turned on and modulated by different ways. One of then is mediated by Ag-Ac reactions and a protein called FAS seems to have an important role in it's modulation. We studied the relation between FAS an the increased apoptosis in undescended testics. Testicular biopsies were done in criptorchid patients during orchidopexy and FAS was measured by immune-techniques...

The role of the human testis in the production of 17beta-estradiol (E(2)) was investigated by determining the concentration of E(2) and testosterone in peripheral and spermatic vein plasma samples. Specimens were obtained from eight normal men, three men with hypogonadism, and two patients with the incomplete form of the feminizing testes syndrome. For comparison, similar studies were performed in four monkeys, 10 mongrel dogs, and 4 additional dogs who were given 1000 IU of human chorionic gonadotropin/day for 5 days...

An Irish Setter with scrotal enlargement had an agglutination titer to Brucella canis of greater than or equal to 1:200, but B canis was not cultured from the blood. Unusual findings included draining ulcers in the scrotum from which B canis was cultured, a necrotic testicle, and inflammation of the entire scotum. Other clinical and postmortem findings were as previously described in other cases of naturally occurring and experimentally induced canine brucellosis.

130 Ram testes have been used in the study, and the following methods were applied to fill and study the testical arteries: röntgenography, stereoröntgenography, corosive method, Indian ink and gel injections. Variabilities occur as to the site where the a.testicularis arises in rams. Individual differences can also be observed in the arrangement of the epididymal arteries, in most cases, however, they arise from the first loops of the convolution. Both epididymal arteries are considerably thinner than the testicular artery, forming 2 independent vessel convolutions, located at both sides of the convolution of the a...

Torsion of the testicle is often due to the "bell-clapper" deformity. This deformity is frequently bilateral. Prevention of future episodes of torsion depends upon the creation of a broad area of dense adhesion between the tunica albuginea and the scrotal wall. The results of this study indicate that this may be best accomplished by creating a window in the tunical vaginalis so that during healing a broad area of the tunica albuginea is held in apposition to a raw surface devoid of tunica vaginalis. Simply suturing the testical to the wall of the hemiscrotum does not always result in permanent fixation...
