Abstract
According to numerous assisted reproductive medicine practitioners, semen with normal characteristics might not require further investigation. However, on the scale of the individual spermatozoon, it is well known that normal morphology does not guarantee optimal nuclear quality. Here, for 20 patients with normal sperm characteristics and a high proportion of spermatozoa with noncondensed chromatin, we subsequently assessed chromatin condensation status (aniline blue staining) and morphology (Papanicolaou staining) of the same 3749 spermatozoa. Although the overall proportion of morphologically normal spermatozoa was not correlated with the overall proportion of spermatozoa with noncondensed chromatin, an individual spermatozoon's morphology appeared to be closely related to its chromatin condensation status. Morphologically normal spermatozoa with noncondensed chromatin were seen in all patients; the proportion averaged 23.3% [min 10.9%-max 44.4%]. Morphologically abnormal spermatozoa were more likely to have noncondensed chromatin than morphologically normal ones (P < 0.0001). Small-, large- or multiple-headed spermatozoa presented the highest degree of noncondensation (>80% for each type), and more than half the vacuolated spermatozoa also presented noncondensed chromatin. However, a morphologically normal spermatozoon may also have a noncondensed chromatin.

Abstract
BACKGROUND Transanal TME is a new approach to performing minimally invasive rectal resection. It is particularly well suited for patients with locally advanced distal rectal cancer and obesity, where the abdominal approach is challenging. Transanal TME can be performed with either TAMIS or TEM. Here, we report our initial experience with transanal TME using TAMIS (TAMIS-TME). METHODS Patients were selected to undergo transanal TME using the TAMIS platform (TAMIS-TME) primarily for malignant disease, but also for select cases of benign disease. Transanal TME defines a "bottom-up" approach to en bloc rectal cancer resection. Transanal TME requires abdominal access for proximal colonic mobilization and is often done in conjunction with a laparoscopic approach. RESULTS During a 32-month period, 20 patients underwent TAMIS-TME with curative intent. The primary indication for transanal TME was distal, locally advanced rectal cancer. The median age of rectal cancer patients at the time of surgery was 57 years (range 36-73 years) with 30% (6) female and 70% (14) male. The median body mass index (BMI) measured was 24 kg/m(2) (range 18-41 kg/m(2)); this included six patients (30%) with obesity (BMI ≥ 30 kg/m(2)). Mean operating time was 243 min (range 140-495 min) with blood loss averaging 153 ml. Postoperative length of stay averaged 4.5 days (range 3-24 days). There was no 30-day postoperative mortality. Surgical complications included wound infection (n = 2), pelvic abscess (n = 4), and prolonged ileus (n = 4). The anastomotic leak rate was 6.7% (1/15). Of the 20 patients who underwent resection, 90% (18/20) had negative margins. Pathologic grading of the TME specimen revealed that 85% (17/20) of transanal TME specimens were found to have "completely" or "near-completely" intact mesorectal envelopes. Data collected during the 6-month median follow-up period revealed that only one patient had developed distant metastasis. There was no locoregional recurrence in any of the patients. CONCLUSIONS Transanal TME is a feasible method for oncologic resection of locally advanced mid- and distal-rectal cancer with curative intent. It has special application for patients with obesity and anatomic constraints such as a narrow male pelvis.

Abstract
Intracytoplasmic morphologically selected sperm injection (IMSI) involves the use of differential interference contrast microscopy at high magnification (at least ·6300) to improve the observation of live human spermatozoa (particularly by showing sperm head vacuoles that are not necessarily seen at lower magnifications) prior to intracytoplasmic sperm injection (ICSI) into the oocyte. However, a decade after IMSI’s introduction, the technique’s indications and ability to increase pregnancy and/or birth rates (relative to conventional ICSI) are subject to debate. In an attempt to clarify this debate, this work performed a systematic literature review according to the PRISMA guidelines. The PubMed database was searched from 2001 onwards with the terms ‘IMSI’, ‘MSOME’ and ‘high-magnification, sperm’. Out of 168 search results, 22 relevant studies reporting IMSI outcomes in terms of blastocyst, pregnancy, delivery and/or birth rates were selected and reviewed. The studies’ methodologies and results are described and discussed herein. In view of the scarcity of head-to-head IMSI versus ICSI studies, the only confirmed indication for IMSI is recurrent implantation failure following ICSI. All other potential indications of IMSI require further investigation.

Abstract
A new era has emerged in rectal cancer surgery--transanal total mesorectal excision (TME). Various platforms have been used to facilitate this novel approach, including transanal minimally invasive surgery (TAMIS) and transanal endoscopic microsurgery. We have previously reported the use of TAMIS-TME. This is a report of the first human case of robotic-assisted transanal surgery for TME.

Abstract
In one-dimensional conductors, interactions result in correlated electronic systems. At low energy, a hallmark signature of the so-called Tomonaga–Luttinger liquids is the universal conductance curve predicted in presence of an impurity. A seemingly different topic is the quantum laws of electricity, when distinct quantum conductors are assembled in a circuit. In particular, the conductances are suppressed at low energy, a phenomenon called dynamical Coulomb blockade. Here we investigate the conductance of mesoscopic circuits constituted by a short single-channel quantum conductor in series with a resistance, and demonstrate a proposed link to Tomonaga–Luttinger physics. We reformulate and establish experimentally a recently derived phenomenological expression for the conductance using a wide range of circuits, including carbon nanotube data obtained elsewhere. By confronting both conductance data and phenomenological expression with the universal Tomonaga–Luttinger conductance curve, we demonstrate experimentally the predicted mapping between dynamical Coulomb blockade and the transport across a Tomonaga–Luttinger liquid with an impurity. When physicists study the characteristics of quantum conductors they usually take great pains to limit the resistance of other elements in the system. But Jezouin et al. show that when a single quantum channel is measured in series with a resistor, it exhibits analogous characteristics to a Tomonaga–Luttinger liquid.

Abstract
CV247 (CV), an aqueous mixture of copper (Cu) and manganese (Mn) gluconates, vitamin C and sodium salicylate increased the antitumour effects of cisplatin (CDPP; cis-diamminedichloroplatinum) in vitro. We hypothesized that the antioxidant and cyclooxygenase-2 (COX-2; prostaglandin-endoperoxide synthase 2) inhibitory components of CV can protect the kidneys from CDPP nephrotoxicity in rats. CDPP (6.5 mg/kg, intraperitoneally) slightly elevated serum creatinine (Crea) and blood urea nitrogen (BUN) 12 days after treatment. Kidney histology demonstrated extensive tubular epithelial damage and COX-2 immunoreactivity increased 14 days after treatment. A large amount of platinum (Pt) accumulated in the kidney of CDPP-treated rats. Furthermore, CDPP decreased renal iron (Fe), molybdenum (Mo), zinc (Zn), Cu and Mn concentrations and increased plasma Fe and Cu concentrations. CDPP elevated plasma free radical concentration. Treatment with CV alone for 14 days (twice 3 ml/kg/day orally) did not influence these parameters. Chronic CV administration after CDPP reduced renal histological damage and slightly decreased COX-2 immunoreactivity, while failed to prevent the increase in Crea and BUN levels. Blood free radical concentration was reduced, that is, CV improved redox homeostasis. CV restored plasma Fe and renal Fe, Mo and Zn, while decreased Pt and elevated Cu and Mn concentrations in the kidney. Besides the known synergistic antitumour effects with CDPP, CV partially protected the kidneys from CDPP nephrotoxicity probably through its antioxidant effect.

Abstract
Accurate incidence estimates are essential for quantifying hepatitis C virus (HCV) epidemic dynamics and monitoring the effectiveness of public health programmes, as well as for predicting future burden of disease and planning patient care. In Egypt, the country with the largest HCV epidemic worldwide, two modelling studies have estimated age-specific incidence rates that, applied to the age pyramid, would correspond to more than 500 000 Egyptians getting infected annually. This is in contrast to figures of the Egyptian Ministry of Health and Population that estimates new infections to be approximately 100 000 per year. We performed new analyses of nationwide data to examine the modelling assumptions that led to these estimates. Thus, we found that the key assumption of these models of a stationary epidemic is invalid. We propose an alternate approach to estimating incidence based on analysing cohort data; we find that the number of annual new infections is <150 000.

Abstract
We study experimentally and theoretically structural defects which are formed during the transition from a laser cooled cloud to a Coulomb crystal, consisting of tens of ions in a linear radio frequency trap. We demonstrate the creation of predicted topological defects ("kinks") in purely two-dimensional crystals and also find kinks which show novel dynamical features in a regime of parameters not considered before. The kinks are always observed at the center of the trap, showing a large nonlinear localized excitation, and the probability of their occurrence saturates at ∼0.5. Simulations reveal a strong anharmonicity of the kink's internal mode of vibration, due to the kink's extension into three dimensions. As a consequence, the periodic Peierls-Nabarro potential experienced by a discrete kink becomes a globally confining potential, capable of trapping one cooled defect at the center of the crystal.

Abstract
Optimal single electron sources emit regular streams of particles, displaying no low-frequency charge current noise. Because of the wave packet nature of the emitted particles, the energy is, however, fluctuating, giving rise to heat current noise. We investigate theoretically this quantum source of heat noise for an emitter coupled to an electronic probe in the hot-electron regime. The distribution of temperature and potential fluctuations induced in the probe is shown to provide direct information on the single-particle wave function properties and display strong nonclassical features.

Abstract
Transanal minimally invasive surgery (TAMIS) is a new technique for the local excision of rectal neoplasia. This platform employs ordinary laparoscopic instruments to achieve high-quality local excision. The TAMIS platform, however, is quite versatile. Described here are applications of TAMIS beyond local excision, ranging from repair of a rectourethral fistula to reverse proctectomy.

Abstract
Résumé
Introduction
Dans l’azoospermie obstructive (AO), les taux d’extraction chirurgicale de spermatozoïdes sont élevés. Cependant, en ce qui concerne les issues des ICSI (Intra cytoplasmic Sperm Injection) chirurgicales, les données de la littérature divergent. Quels sont, dans notre équipe, les taux d’extraction de spermatozoïdes après aspiration épidydimaire (MESA) et après extraction testiculaire (TESE) dans l’AO ? Les taux de grossesses, les taux de fausses couches spontanées et d’accouchements diffèrent-ils en fonction de l’origine du sperme ?
Matériels et méthodes
L’étude a rétrospectivement inclus 48 couples dont l’homme présente une azoospermie obstructive pure et ayant bénéficié d’un prélèvement chirurgical de spermatozoïdes associant systématiquement MESA et TESE. Les ICSI ont été réalisées de manière asynchrone. À chaque fois que cela était possible, la première ICSI a été réalisée avec des spermatozoïdes épididymaires.
Résultats
Pour les 48 couples, 99 ICSI ont été réalisées. Quinze couples ont réalisé 24 ICSI-TESE car l’aspiration épididymaire était négative. Onze couples ont réalisé 20 ICSI-TESE car la qualité du prélèvement épididymaire n’était pas satisfaisante (vitalité spermatique réduite le plus souvent). Vingt-deux couples ont réalisé 22 ICSI-MESA en première intention puis en cas d’échec, 11 couples ont réalisé 12 ICSI-MESA et dix couples ont réalisé 20 ICSI-TESE. Alors que les nombres d’ovocytes injectés (7,1±4,1 vs 6,9 ±3,6 P: 0,8) et d’embryons obtenus (4,5±3,0 vs 4,7±2,7; P: 0,7) ne sont pas significativement différents dans les deux groupes d’ICSI, les nombres d’embryons de top qualité (2,4±1,9 vs 3,6±2,0 P: 0,005) et d’embryons congelés (0,9±1,8 vs 1,7±1,9 P: 0,04) sont significativement supérieurs dans le groupe TESE. Le nombre de grossesse par ponction est supérieur dans le groupe TESE (58,5 % vs 26,5 %, P: 0,002).
Conclusion
L’approche de notre centre a la particularité d’associer systématiquement un prélèvement testiculaire au prélèvement épididymaire chez tout homme présentant une azoospermie obstructive alors que la plupart des autres études rapportées se limitent à l’exploration épididymaire si cette dernière est positive lors de l’examen extemporané. Alors que classiquement, on rapporte 100% de positivité lors du prélèvement épididymaire chez l’homme atteint d’une azoospermie obstructive, dans notre étude, plus de la moitié des explorations épididymaires s’est avérée inexploitable. La qualité embryonnaire et les taux de grossesses sont meilleurs avec des spermatozoïdes testiculaires. L’association de ces 2 sites de prélèvement (MESA et TESE) peut être complémentaire et utile pour le couple et l’issue de sa prise en charge en AMP sans pour autant entraîner un sur-risque pour l’homme dans les suites de la chirurgie.

Abstract
BACKGROUND For those patients undergoing laparoscopic colorectal surgery who have had prior abdominoplasty, cosmetic outcome is important and the technical considerations for laparoscopy in post-abdominoplasty patients have not been previously addressed. The aim of the present study was to define the technical approach to the post-abdominoplasty patient undergoing laparoscopic colorectal surgery after abdominoplasty. METHODS Utilizing the technical approach described, eleven patients underwent laparoscopy after prior abdominoplasty over a 7-year period. RESULTS The majority of patients (10/11) felt their laparoscopic colorectal resection had no adverse effect on the aesthetics of their prior abdominoplasty. From a surgeon's standpoint, the only significant challenge was due to the loss of abdominal wall compliance. CONCLUSIONS The surgical approach to laparoscopic colectomy in the post-abdominoplasty patient requires careful planning. Cosmetic outcome is a particularly important consideration for this subset of patients, and this should be appreciated by the operating surgeon.

Abstract
OBJECTIVE Incidents related to transport of critically ill patients have been extensively reported. The objective of this study was to determine the effect of an interdisciplinary preventive programme used by all intensive care unit team members involved in patients' transport on the rate of these incidents. METHODS A clinical quality improvement audit using a prospective pre and post intervention design was performed among medical and surgical patients hospitalised in intensive care who required intra or inter-hospital transport. RESULTS A total of 180 transports occurred in the pre-implementation phase of the study and 187 transports in the post-implementation phase. A 20% absolute reduction of incidents was observed (57.2% vs. 37.4%, p<0.001). Statistically significant reductions were obtained for the technical problems category of incidents (25% vs. 7.5%, p<0.001) as well as the problems related to patient's mobilisation category (14.4% vs. 7.5%, p=0.05). Clinically significant trends were also observed for the clinical deterioration (24.4% vs. 17.1%, p=0.11) and undesired delay before test (23.9% vs. 17.6%, p=0.14) categories but did not reach statistical significance. CONCLUSIONS A preventive programme applied by all care providers involved in transport of critically ill patients was associated with a reduction of incidents. The application of such a programme should be acknowledged as a standard of care considering the risks inherent to the transportation of ICU patients.

Abstract
The approach to local excision of benign and early-stage, well-selected neoplasms of the rectum continues to evolve. We demonstrate here that local excision of a rectal neoplasm using the da Vinci Robotic Surgical System can be successfully performed. To our knowledge, this is the first time robotic transanal surgery (RTS) has been used in this manner.
