F López-Gatius, Rhf Hunter
Temperature gradients in female reproductive tissues seem to influence the success of key processes such as ovulation and fertilization. The objective of this study was to investigate whether pre-ovulatory follicles are cooler than neighbouring uterine tissue and deep rectal temperatures in lactating dairy cows under heat stress conditions. Temperatures within the pre-ovulatory follicle, on the uterine adjacent surface and 20 cm deep within rectum, were measured using fine thermistor probes within 45 min after sunrise (dawn)...

There have been many studies on dopamine active transporter (DAT) in humans and laboratory animals; however, there is a lack of information on DAT in brine shrimp. In this study, we demonstrated the neuronal and nonneuronal characteristics of DAT-synthesizing (DAT(+) cells) during development of brine shrimp. In neuronal cells, the DAT(+) neurons in the central body and lobes of a protocerebrum (PC) controlled the deutocerebrum. The sensory cells of nauplius eyes projected their decussated axons to the PC, and the DAT(+) cells at the posterior region were associated with migration and control of the 10 posterior neurons during the early nauplius stage...

Gastrointestinal symptoms are very common in systemic lupus erythematosus (SLE). Lupus "enteritis" is very responsive to treatment but can have devastating consequences if not detected. Most descriptions of enteritis involve the small and large bowel. This is the first report of lupus "enteritis" involving the entire gastrointestinal tract from the esophagus and stomach to the rectum. Lupus "enteritis" is another cause of upper gastrointestinal involvement in SLE (involving even the esophagus and stomach) in addition to involvement of the lower intestinal tract...

BACKGROUND: Radiotherapy in the treatment of prostate cancer is well established. Intestinal complications following radiotherapy are divided into acute and chronic toxicity. Chronic complications like perforation and fistula formation to the rectum are rare and difficult to treat. MATERIALS AND METHODS: In case of chronic radiotherapy complications and particularly chronic fistula formation to the rectum, evidence is low. Therefore, an overview of the available literature of surgical therapy strategies is given...

BACKGROUND: We aimed to clarify the long-term outcomes of patients with T1 colorectal carcinoma (CRC) after endoscopic resection (ER) and surgical resection. METHODS: We examined T1 CRC patients treated during 1992-2008 and who had ≥5 years of follow-up. Patients who did not meet the curative criteria after ER according to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines were defined as "non-endoscopically curable" and classified into three groups: ER alone (Group A: 121 patients), additional surgery after ER (Group B: 238 patients), and surgical resection alone (Group C: 342 patients)...

BACKGROUND: Radiotherapy reduces the risk of local recurrence in rectal cancer. However, the optimal radiotherapy fractionation and interval between radiotherapy and surgery is still under debate. We aimed to study recurrence in patients randomised between three different radiotherapy regimens with respect to fractionation and time to surgery. METHODS: In this multicentre, randomised, non-blinded, phase 3, non-inferiority trial (Stockholm III), all patients with a biopsy-proven adenocarcinoma of the rectum, without signs of non-resectability or distant metastases, without severe cardiovascular comorbidity, and planned for an abdominal resection from 18 Swedish hospitals were eligible...

We report the case of a 35-year-old homosexual man with previous history of HIV, with primary chacre in the rectum. We believe this paper is significant because the diagnosis of rectal ulcer is more common in recent years, however rectal syphilis is a poorly recognized entity, especially with primary chancre formation.

Attention is increasingly being focussed on probiotics as potential agents to restore or improve gastrointestinal (GI) transit. Determining mechanism of action would support robust health claims. The probiotic bacterium Bifidobacterium lactis HN019 reduces transit time, but its mechanisms of action and effects on motility patterns are poorly understood. The aim of this study was to investigate changes in GI motility induced by an extract of HN019 on distinct patterns of colonic motility in isolated rat large intestine, compared with a known promotility modulator, prucalopride...

Today, we are experiencing a real cultural revolution in the therapeutic approach to cancer of the colon - rectum, that, by orphan disease, it is now becoming an important paradigm of scientific innovations and concepts. Survival of patients with metastatic colorectal cancer (m-CRC) has been significantly improved with the introduction of the monoclonal antibodies that have as target the vascular endothelial growth factor (VEGF) and the epidermal growth factor receptor (EGFR). Novel agents such as aflibercept and regorafenib have recently been approved...

Intravenously administered for the treatment of rectum cancer, irinotecan produces severe side effects due to very high plasma concentrations. A novel irinotecan-encapsulated double reverse thermosensitive nanocarrier system (DRTN) for rectal administration was developed as an alternative. The DRTN was fabricated by dispersing the thermosensitive irinotecan-encapsulated solid lipid nanoparticles (SLN) in the thermosensitive poloxamer solution. Its gel properties, pharmacokinetics, morphology, anticancer activity and immunohistopathology were assessed after its rectal administration to rats and tumor-bearing mice...
