Abstract:
Anal cancer may be an emerging clinical problem in HIV-infected women particularly in resource-limited settings. Human papillomavirus (HPV) infection is a precursor to anal cancer and is prevalent in HIV-infected women, but the natural history of HPV infection and anal cancer precursors is not well described in this population. It is not known which specific dysplastic lesions in the anus are most likely to progress, and whether treatment of high grade squamous intraepithelial lesion reduces the incidence of anal cancer in women. Cervical HPV infection and associated lesions may be related to

Abstract The benefit of treating anal precancerous lesions to reduce anal cancer progression was recently shown in people living with HIV.

Kukalová-Peck has provided evidence that insect wings evolved from primitively moveable exite lobes of leg podomeres proximal to the coxa. Reinterpretation of previous experimental findings suggests that this hypothesis, as currently formulated, is only partly correct. The costal–subcostal field is derived from an epicoxal exite, but the radial–medial and cubital–anal fields of the wing have arisen from epicoxal endite and (or) subcoxal exite and endite lobes. Wings thus have a complex origin: limb exite plus endite.

Background/Purpose: This study summarizes the surgical treatment options and their clinical efficacy for postoperative residual rectourethral fistula following anoplasty in patients treated in our department from July 2005 to July 2012. Methods: For 38 cases of postoperative residual rectourethral fistula following anoplasty, according to differences in anal appearance and functionality, either an anterior sagittal or a posterior sagittal surgical rectourethral fistula repair procedure was performed. Results: The residual rectourethral fistula following anoplasty was an obvious tube-like struc

Abstract:
570 Background: Despite potential oncologic gains from using radiotherapy in patients with inflammatory bowel disease (IBD), it has historically been contraindicated due to increased acute gastrointestinal (GI) toxicity. Yet recent published literature is mixed with regards to toxicity outcomes in these patients. In this study, we examine GI, genitourinary (GU), and skin toxicity in IBD patients compared to non-IBD patients both treated with external beam radiation therapy (EBRT) for anal or colorectal cancer (CRC). Methods: Anal and CRC patients who received EBRT were included in this single

Abstract:
Smooth muscle preparations from the circular muscle layer of the most distal rectum and the proximal and distal human internal anal sphincter (IAS) mounted in organ baths to record isometric tension developed spontaneous tension. Transmural electrical field stimulation (TMS) induced frequency- and impulse duration-dependent relaxations sensitive to tetrodotoxin in the stimulation range of 0.5-40 Hz and 0.04-0.6 ms. Poststimulus contractions were most frequent and prominent in rectal preparations. Maximal relaxations were comparable in the three locations and were achieved at 10 Hz and 0.4 ms.

Because anal cancer is uncommon and carries a significant social stigma, this disease has rarely been studied in a prospective fashion, creating a large knowledge gap of which biological factors can improve treatment responses, particularly the microbiome which regulates many facets of oncobiology. Methods: We collected microbiome samples before, during, and after definitive chemoradiation for localized anal cancer as part of an IRB-approved institutional clinical trial (2017-0606). Sample

The real hemorrhoidal plexuses (internal) are normal anatomical structures that play an important physiological role in perfecting continence in synergy with the sphincter system.

Abstract:
Field trials were conducted in central Australia to evaluate the ability of various olfactory lures to attract feral cats (Felis catus L.). Ten food-based lures, one plant extract and two scent-based lures (anal-gland preparations from male and female cats) were evaluated on the basis of visitation rates and elicited behavioural responses. A visual lure composed of bird feathers was also tested in conjunction with the scent-based lures. One food-based lure (sun-rendered prawn) and both of the scent-based lures were found to attract feral cats. The visual lure did not enhance the attractiveness

Although the species are significantly different, they cannot be fully separated using these characters. I suggest that electrophoretic techniques are needed for precise identifica
