#1
Lior Segev, Gokhan Ozuner
Colonic diverticulosis prevalence is gradually increasing worldwide. 3-15% of the patients with diverticulosis will bleed at some point. The risk for rebleeding after the first episode is substantial but varies in the literature between 13-48%. We analyze risk factors for diverticular bleed and management options for initial and recurrent diverticular bleeding. A review of the literature on this subject is presented.

Despite being initially considered a benign disease, it is widely thought nowadays that endometriosis and especially ovarian endometriomas are neoplastic conditions with the potential to become malignant. This review was conducted to summarize, in a concise and systematic manner, the available scientific data relating endometriosis to ovarian cancer, published in the past five years. After reading abstracts and applying our predefined inclusion and exclusion criteria, a final list of 11 scientific papers was obtained and subjected to review...

An 81-year-old female patient was admitted to our institute because of abnormal X-ray results. Chest computed tomography showed a 7.7 × 5.3 cm mass located in the left lower lobe and multiple swollen lymph nodes. 18F-fluorodeoxyglucose-positron emission tomography indicated high standard uptake values in the mass and swollen lymph nodes. The patient was diagnosed with stage cT3N2M0-IIIA squamous cell carcinoma. Although the patient had multiple lymph node metastases and severe obstructive pulmonary function, four cycles of platinum doublet chemotherapy were initially performed and no side effect greater than grade 3 was experienced...

I bought a robotic vacuum cleaner this summer and set it to work. Although my initial expectations were not high, my robot (christened Buddy) finished its cleaning cycle, and then insistently demanded that I empty its dust collection box. As I took the box out, my jaw dropped. I live in a modern house, we don't have pets, and I like to think that I keep it reasonably dust free. But, there was much dust in that box. And when I ran it again 2 days later, the same thing happened. And indeed, every 2 days, Buddy dutifully goes to work, and sucks up a similarly impressive quantity...

For some time, the euphemism "horses sweat, men perspire, but ladies merely glow" was scientifically supported. Initial studies examining gender differen0063es in sweat production generally observed that women sweat less than men during heat exposure (i.e. they merely glow).

BACKGROUND AND PURPOSE: Data on mortality in patients with epilepsy have been available since the 1800s. They consistently show a 2-3-fold increase compared to the general population. Despite major advances in diagnostic tools and treatment options, there is no evidence for a decrease in premature deaths. The temporal trend of mortality in a hospital-based epilepsy cohort over three decades was assessed. METHODS: A hospital-based incidence cohort was recruited from a specialized epilepsy outpatient clinic at Innsbruck Medical University between 1980 and 2007, divided by decade into three cohorts and followed for 5 years after initial epilepsy diagnosis...

Burn injuries are known to compromise host immune defenses through disruption of mucocutaneous barriers and suppression of cell-mediated immune responses, which may render patients with burn injuries susceptible to viral infections in the days to years after an initial insult. We report a case of verrucae planae developing as a secondary condition confined to former xenograft sites in a child, appearing more than 3.5 years after initial second-degree burn injuries. Only a few reports have previously described the development of verrucae in former burn sites, with most reporting latency to onset of verrucae appearance of months rather than years...

BACKGROUND: Suffering profoundly touches the human being's inner existence. The different faces of suffering may yet be unknown, and therefore, it is important to further explore suffering in order to reach a new and deeper understanding of it and its alleviation. THE AIM AND RESEARCH QUESTIONS: The aim of this study was to expand the understanding of suffering. The research questions are what is suffering as described by the human beings themselves and what initiates a movement in suffering towards its alleviation? RESEARCH DESIGN, PARTICIPANTS AND RESEARCH CONTEXT: The study uses a hermeneutical approach and hermeneutical reading...

Experiments were performed on the snails trained in conditioned food aversion for 3 days. Injection of TDZD-8 (glycogen synthase kinase-3 inhibitor, 2 mg/kg) in combination with reminder (presentation of a conditioned food stimulus) led to memory impairment developing 3 days after inhibitor/reminder exposure and followed by spontaneous recovery in 10 days. Injections of TDZD-8 in a dose of 4 or 20 mg/kg before reminder were shown to cause amnesia that persisted for more than 10 days. Memory recovery during repeated training was observed at the earlier period than after initial training...

Pathomorphological study of trephinobiopsy specimens from 129 patients with lymphoproliferative and myeloproliferative diseases was carried out over the course of chemotherapy. Combinations of initial and manifest myelofibrosis (loose network of reticulin fibers and extensive network of reticulin and collagen fibers, respectively) predominated at the debut of chronic myeloid leukemia, chronic lymphoid leukemia, and multiple myeloma. Manifest myelofibrosis was detected in patients with chronic myeloid leukemia without hematological response (failure of normalization of hematological values) and in patients with progressing and relapsing multiple myeloma...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening dermatological conditions that are characterized by mucosal erosions, epidermal detachments and erosions. The most common causes of SJS and TEN are drugs; other causes such as systemic lupus erythematosus (SLE), vaccinations and infections have been rarely implicated. We present the case of a 14-year-old female patient with acute pancreatitis as an initial manifestation of systemic lupus erythematosus, complicated by the toxic epidermal necrolysis with a fatal outcome...

Non-academic members of research teams, such as community members, can perceive traditional human subjects protection training as lacking in cultural relevance. We present a case exemplar of the development of a human subjects protection training for research staff with limited English proficiency and/or no or limited research experience. Seven modules were adapted for language, cultural examples, etc., from the standard Collaborative Institutional Training Initiative (CITI) human subjects protection training...

We suggest and explore a novel route towards organic photodetectors sensitive to the circular polarization state of light. For this, we insert fullerene-blended thin films of homochiral squaraine compounds acting as a highly circular dichroic active layer into conventional bulk hetero-junction photodiodes. Initially, we discuss steady-state characterization of photodiodes with unpolarized light. The homochiral, l-proline derived squaraine compounds are obtained via a chiral pool synthesis in sizable quantities...

Zhouting Rong, Antonio M Echavarren
The polycyclisation of polyenynes catalyzed by gold(i) has been extended for the first time to the simultaneous formation of up to four carbon-carbon bonds, leading to steroid-like molecules with high stereoselectivity in a single step with low catalyst loadings. In addition to terminal alkynes, bromoalkynes can also be used as initiators of polyene cyclisations, giving rise to synthetically useful cyclic bromoalkenes.

H F Chan, S Ma, J Tian, K W Leong
The rapid advances in synthetic biology and biotechnology are increasingly demanding high-throughput screening technology, such as screening of the functionalities of synthetic genes for optimization of protein expression. Compartmentalization of single cells in water-in-oil (W/O) emulsion droplets allows screening of a vast number of individualized assays, and recent advances in automated microfluidic devices further help realize the potential of droplet technology for high-throughput screening. However these single-emulsion droplets are incompatible with aqueous phase analysis and the inner droplet environment cannot easily communicate with the external phase...

Mitophagy occurs during ischemia/reperfusion (I/R) and limits oxidative stress and injury. Mitochondrial turnover was assessed in patients undergoing cardiac surgery involving cardiopulmonary bypass (CPB). Paired biopsies of right atrial appendage before initiation and after weaning from CPB were processed for protein analysis, mitochondrial DNA/nuclear DNA ratio (mtDNA:nucDNA ratio), mtDNA damage, mRNA, and polysome profiling. Mitophagy in the post-CPB samples was evidenced by decreased levels of mitophagy adapters NDP52 and optineurin in whole tissue lysate, decreased Opa1 long form, and translocation of Parkin to the mitochondrial fraction...
