In this paper, we report on the charge/discharge characteristics at high and low tempera 4 tures that are expected with solid-state thin film lithium 3. To reduce interfacial resistance, the oxide buffer layer is inserted at the cathode interface. A sil icon layer is also inserted at the anode interface in order to acteristics at room temperature (25˚C) were investigated prevent electrochemical reduction of the solid electrolyte. Specifically, the discharge capacity was 89% of the capacity at a low rate, cathode film was deposited by sputtering; the buffer layer, which indicates that this battery has excellent power char solid electrolyte, and Si layer were deposited by pulsed laser acteristics. Thus, 24C All steps after the solid electrolyte film is deposited must be is the current value that can completely charge/discharge carried out under a dry atmosphere. This indicates that the thin film battery is capable of completing 90% charge/discharge in less than 3 minutes. Nevertheless, the capacity itself is not very large because the battery is made of “thin” films.

The desk top study is a review of the scientific literature and live export industry practices to investigate the use and potential benefits of electrolyte supplements during shipping. It identifies sea transport stress factors and describes the physiological and clinical effects of these in cattle and sheep and considers the benefits of electrolyte supplementation in treating these clinical syndromes. Recommendations for research are made to enable the development of robust and effective guidelines on the best use of electrolytes. It is proposed that field trials and development of best practice guidelines be carried out in the second stage of this project along with the development of a communication strategy to maximise uptake of the guidelines by industry. The main functions of electrolytes are to satisfy dietary nutrient requirements and maintain the acid-base balance (neutral pH) of the body. Hence, electrolyte treatments or supplements aim to replenish lost electrolytes and/or correct an acid-base imbalance and there are a number of products currently available in Australia that can do this during the live export of cattle and sheep. To be effective, electrolytes need to alleviate heat and nutritional stress that occurs during live export. Correcting the physiological imbalances that occur as a result of these stresses is the key to the best use of electrolytes. There is insufficient data to draw any conclusions on the cost-benefits of electrolytes during shipping or to make any recommendations on their best use. What electrolyte formulation is required to alleviate heat and fasting stress during shipping? What are the benefits of providing the correct electrolyte supplement during shipping? The actual physiological state of cattle and sheep during shipping has not been confirmed. The literature suggests that for cattle, heat stress encountered during shipping will result in metabolic acidosis, while experience suggests that respiratory alkalosis is a significant problem. For sheep, research findings suggest that glucose supplementation may be required to treat inanition, the main cause of deaths during shipping. The current use of electrolytes by the industry is not consistent with these findings. Land-based studies on the benefits of electrolytes are inconclusive and do not allow any conclusions to be drawn. A general pattern of electrolyte use and industry views on the benefits of electrolytes cannot be determined due to the differences in opinion that exist in the industry. Hence, we recommend that specific research under commercial conditions be conducted into the benefits and costs of electrolyte supplements during shipping. Following are the key findings of this review and recommendations for research to provide the necessary information for guidelines on the best use of electrolytes during shipping to be developed. Sodium, potassium, chloride and bicarbonate have the greatest effect on acid-base balance. Electrolyte supplements replenish lost electrolytes and/or correct an acid-base imbalance. Sea transport stress factors and their effects the main causes of stress in cattle and sheep during sea transport are: Heat; Poor ventilation; and Fasting. Heat, poor ventilation and nutritional stress result in: Hyperthermia (heat stress); Pneumonia (respiratory distress); Starvation; and Dehydration. The actual physiological state of cattle and sheep during sea transport is not confirmed. To be effective, electrolyte supplements used during shipping may need to do one or more of the following: Correct electrolyte deficiencies; Correct acidosis; Correct alkalosis; and Provide a mechanism for glucose supplementation. All of the currently available electrolytes that are suitable for use on a livestock vessel could potentially alleviate stress in cattle and sheep during shipping. An electrolyte supplement for cattle and sheep during shipping should include at least: glucose; sodium chloride; sodium bicarbonate; and potassium chloride. Constituent concentrations of electrolyte supplements for use during shipping would depend on the species and the predominant clinical syndrome that occurs during shipping. Results of land-based studies on the effects of short term electrolyte supplementation on alleviating stress in beef cattle do not allow conclusions to be drawn on the benefits of electrolytes during short-haul shipping. Results of land-based studies on the effects of long term electrolyte supplements indicate that continual electrolyte supplementation of cattle and sheep during long-haul sea transport could be beneficial.

Primary Sclerosing Cholangitis, Part 1: Epidemiology, Etiopathogenesis, Clinical Features, and Treatment James H. Dr Ali is a consequent decrease in survival (median, approximately 20 years) research fellow in the Division of and quality of life. Here, in the first of a 2-part series, we provide a review and Address correspondence to: Dr Keith D. Numerous agents have been tested, although none have yielded convincingly promising results. Biliary epithelial cells (ie, cholangiocytes) exist in an environment with multiple potential etiologic mediators of hepatobiliary injury. Approximately 95% of bile acids are reabsorbed in the terminal ileum and, together with other intestinal molecules, are transported back to the liver via the enterohepatic circulation. Portal blood flows into hepatic sinusoids, wherein hepatocytes may take up and modify these molecules and secrete them into bile, which is synthesized by hepatocytes and delivered into canaliculi by means of specialized membrane transporters. Canalicular bile drains into the biliary tree and is modified by cholangiocytes as it percolates through the biliary tree. Cholangiocytes recognize (eg, through cell surface receptors) and react to various molecules and may release chemokines/ cytokines, growth factors, and morphogens, initiating both autocrine and paracrine signaling cascades. With respect to the source of hepatobiliary injury, it remains uncertain whether there is (1) increased exposure to microbial molecules (eg, through the enterohepatic circulation, potentially facilitated by compromised intestinal barrier function), (2) alteration to the repertoire of microbial and other intestinal molecules (eg, due to microbial dysbiosis, xenobiotics), and/or (3) an aberrant or exaggerated cholangiocyte (or another hepatic cell) response to these molecules (eg, increased induction of cholangiocyte senescence and the senescence-associated secretory phenotype).

The document relates the science of pain to the clinical setting and explains the role of psychological, physical, interventional and complementary therapies in cancer pain. It is directed at physicians and other healthcare professionals who treat pain from cancer at any stage of the disease with the hope of raising awareness of the types of therapies that may be appropriate and increasing awareness of the role of the pain specialist in cancer pain management, which can lead to greater dialogue and liaison between oncology, specialist pain and palliative care professionals. The document is accompanied by information for patients that can help them and their carers understand the available techniques and that will support treatment choices. Methods this document has been produced by a consensus group of relevant healthcare professionals and patients’ representatives, making reference to the current body of evidence relating to cancer pain. In order to address these weaknesses, it is suggested that a more comprehensive model of cancer pain management is needed that is mechanism-based and multimodal, using combination therapies including interventions where appropriate, which is tailored to the needs of an individual, with the aim of optimising pain relief while minimalising adverse efects. A knowledge of these mechanisms and the ability to decide whether a pain is nociceptive, neuropathic, visceral or a combination of all three will lead to best practice in pain management. Accurate and meaningful assessment and reassessment of pain is essential and optimises pain relief. History, examination, psychosocial assessment and accurate record keeping should be routine, with pain and quality of life measurement tools used where appropriate. Combining these treatments with pharmacological and non-pharmocological methods of pain control can optimise pain relief, but the limitations of these treatments must also be acknowledged. Cancer pain is often under-reported and under-treated for a variety of complex reasons, partly due to a number of beliefs held by patients, families and healthcare professionals. Group format pain management programmes could contribute to the care of cancer survivors with persistent pain.

The foreskin will sampling may be necessary if a visible lesion is obviously not be present in penectomies from large or if the lesion approaches the margin at circumcised males. Carefully examine the surfaces of the specimen, keeping in mind that the vast majority of penile neoplasms arise from the surface epithelium Penectomies of the glans and from the undersurface of the foreskin. Neoplasms may be concealed by the the diverse findings encountered in penectomies foreskin, so be sure to retract this skin fold and range from the essentially normal penis removed look at the entire surface including the epithelium from a patient undergoing a sex change operation lining the deep recesses of the coronal sulcus.

For of these components cannot be included in a tumors that involve the urethra, determine the single section, submit each component individu maximum tumor extension by submitting sec ally. Remove the foreskin from the uncircumcised tions at regular intervals along the entire length penectomy. The foreskin should then be separately processed according to the guidelines given pre Important Issues to Address viously in the section on the foreskin. The deep structures of the penis are most easily visualized in Your Surgical Pathology when the penis is sectioned in two different Report on Penectomies planes. For larger specimens, it is not practical to submit all of the chips for histologic evaluation. Needle biopsies of the prostate consist of delicate Although six to eight tissue cassettes are gener and thin cores of tan soft tissue. Measure each ally sufficient to detect the vast majority of inci piece of tissue, and document the total number dental carcinomas, the sensitivity of sampling can of pieces before carefully transferring them into be increased by selectively submitting those chips a tissue cassette. As is true for any small biopsy, that appear yellow, indurated, or in any other do not use forceps to pick up these biopsies, way grossly suspicious for carcinoma. More because forceps can squeeze and distort the extensive sampling is warranted in specimens tissue. Have the histology laboratory section from younger patients, since even a small focus of these biopsies at multiple levels, then have them carcinoma in these men may require aggressive stain alternating levels for routine histology. For patients under the age of 65, consider sections are later needed for additional studies submitting the entire specimen for histologic. Similarly, if cancer is identified histo will be readily available, and diagnostic material logically in a specimen that was partially submit will not be lost during sectioning of the tissue ted, the entire specimen should be submitted block. Specimensobtainedbyopenenucleationare either partially or totally intact nodules, but the Transurethral Resections anatomic orientation of these nodules is usually and Open Enucleations not practical or possible. After weighing and mea suring the tissue, serially section the specimen at 2 to 3-mm intervals. Note the appearance of Frequently, the central region of the prostate is the cut surface. Again, extensively sample the removed—either by transurethral resection or by specimen to detect incidental carcinomas. Submit open enucleation—to relieve symptoms of uri up to six to eight cassettes of tissue. As was true nary obstruction caused by nodules compressing for the prostate chips, remember to selectively the prostatic urethra. Although the majority of sample areas that appear grossly suspicious for these nodules are entirely benign, a small, yet carcinoma. Tissue fragments obtained from transurethral Radical Prostatectomies resections of the prostate—referred to as prostate chips—are generally tan, rubbery, and cylindrical. The total number of chips resected varies greatly One of the challenges of the dissection of radical from case to case. Measure the combined weight prostatectomies is to find a balance which will 176 177 178 Surgical Pathology Dissection maximize prognostic information while mini recent fixation protocols that utilize microwave mizing the number of tissue cassettes submitted. Indeed, radical prostatectomy specimens gross appearance of cancer and non-neo-plastic can now be fixed and sectioned on the same day prostate tissue can be hard to recognize. A number of the gross features the distal (apical) margin can be submitted in one of prostate cancer are outlined in Table 31-1 and oftwoways. Onemethodistosubmitthismargin can be helpful in distinguishing carcinoma from as a thinly shaved section. Amputate the distal 1 cm of the apex, Orient the prostate by locating the seminal vesi then section this apical cone at right angles to the cles and vasa deferentia. Thelattertech into the posterior aspect of the base (proximal end) nique allows for a more accurate assessment of of the gland and provide a landmark that is quick exactly how close the cancer approaches the distal and easy to find. If the proximal (bladder neck) base, the apex (distal end) of the prostate narrows and distal (apical) margins are taken as shave and becomes cone shaped. The contour of the sections, these sections should be very thin (1 mm gland can be used to distinguish the anterior and in thickness). The anterior sur among pathologists is that these sections are taken face of the prostate is rounded and convex, while to assess the status of the prostatic urethral the posterior surface is broad and flat. Once transected intact prostate for asymmetry, and palpate it for during surgery, the urethra retracts into the areas of induration. Fixation of the prostate before sec on these margin sections, and you should avoid tioning permits thinner sectioning of the gland thetendencytosubmitthickdoughnut-shaped and better assessment of the margins. It is not necessary to submit Location: the cut surface of the normal prostate shows entire tips of the seminal vesicles. Most carcinomas arise peripherally in the posterior tion the prostate at 2 to 3-mm intervals from and posterolateral portion of the gland. Do not use the urethra as a point of hyperplastic nodules tend to be located centrally around reference for these sections, because this structure the urethra. In Texture: Carcinomas tend to be solid and homogeneous, stead, section the prostate perpendicular to the while non-neoplastic prostate tissue is often spongy and broad flat posterior surface of the gland. Each individual slice should Color: Carcinomas vary in color from gray to brown to be intact, uniformly thin, and surrounded by a yellow. Sometimes these colors contrast sharply with the uniform tan appearance of non-neoplastic prostate. Structural Alterations: Prostatic carcinomas often cause structural changes that are apparent on close inspection Lay the individual slices out sequentially from of the cut surface. Be careful to asymmetry between the two sides of the gland and maintain the orientation. One remember the location of each individual slice simple method is to fasten the slices together with within the prostate. The arms of the U point to the posterior surface of Radical prostatectomies are usually accompanied the gland, and its convexity points to the anterior by a dissection of the pelvic lymph nodes.
