Abstract
PURPOSE To evaluate the benefit of targeted antibiotic prophylaxis (TAP) based on rectal swab culture in comparison with standard empiric antimicrobial prophylaxis in patients undergoing transrectal ultrasound-guided needle biopsy of the prostate (TRUS-BP), as well as to assess rate of fecal carriage of Fluoroquinolone-resistant Enterobacterales FQRE. PATIENTS AND METHODS We prospectively analyzed data that randomized 157 patients within two groups: (G1) TAP according to rectal swab performed 10 days before PB; (G2): empirical antibiotic prophylaxis with ciprofloxacin. Prevalence of FQRE digestive carriage and risk factors were investigated. Incidence of infectious complications after (TRUS-BP) in each group was compared. RESULTS G2 included 80 patients versus 77 in G1. There was no difference between the two groups regarding age, diabetes, prostate volume, PSA, number of biopsy cores, and risk factors for FQRE. In G2, the prevalence of FQRE digestive carriage was 56.3% all related to E. coli species. In the case of digestive carriage of FQRE, TAP according to the rectal swab culture with third-generation cephalosporins was performed in 73.3%. Patients with FQRE had history of FQ use within the last 6 months in 17.8% (p = 0.03). Rate of febrile urinary tract infection after PB was 13% in G1 and 3.8% in G2 (p = 0.02). CONCLUSIONS Incidence of FQ resistance in the intestinal flora of our local population was prevalent. Risk factor for resistance was the use of FQ within the last 6 months. TAP adapted to rectal swab, mainly with third-generation cephalosporins, significantly reduced the rate of infectious complications after (TRUS-BP).

Abstract
Membrane nano-inclusions (NIs) are of great interest in biophysics, materials science, nanotechnology, and medicine. We hypothesized that the NIs within a biological membrane bilayer interact via a simple and efficient interaction potential, inspired by previous experimental and theoretical work. This interaction implicitly treats the membrane lipids but takes into account its effect on the NIs micro-arrangement. Thus, the study of the NIs is simplified to a two-dimensional colloidal system with implicit solvent. We calculated the structural properties from Molecular Dynamics simulations (MD), and we developed a Scaling Theory to discuss their behavior. We determined the thermal properties through potential energy per NI and pressure, and we discussed their variation as a function of the NIs number density. We performed a detailed study of the NIs dynamics using two approaches, MD simulations, and Dynamics Theory. We identified two characteristic values of number density, namely a critical number density n c = 3.67 × 10-3 Å-2 corresponded to the apparition of chain-like structures along with the liquid dispersed structure and the gelation number density n g = 8.40 × 10-3 Å-2 corresponded to the jamming state. We showed that the aggregation structure of NIs is of fractal dimension d F < 2. Also, we identified three diffusion regimes of membrane NIs, namely, normal for n < n c, subdiffusive for n c ≤ n < n g, and blocked for n ≥ n g. Thus, this paper proposes a simple and effective approach for studying the physical properties of membrane NIs. In particular, our results identify scaling exponents related to the microstructure and dynamics of membrane NIs.

Abstract
Microemulsions are excellent systems for transdermal delivery of multifunctional drugs because they have the potential to improve drug absorption/permeation and handling limitations. Biocompatible polymers are used as a coating of microemulsions to avoid the interactions that can occur between the microemulsions and the skin. Thus, they protect and lubricate these transporter nanovesicles. In this paper, we studied decane/water microemulsions covered with hydrophobically modified PEO polymer (PEO-m). To reveal the effect of hydrophobically modified PEO (PEO-m) polymer on the shape, the micro-arrangement and the dynamics of the microemulsions, we used an integrated strategy combining Molecular Dynamics simulation (MD), Small-Angle Neutron Scattering experiments (SANS), and the Ornstein-Zernike integral equations with the Hypernetted Chain (HNC) closure relation. We determined the microemulsion shape in vitro using the renormalized intensities spectra from SANS experiments. We discussed the micro arrangements of microemulsions, in vitro and in silico, employing the pair correlation function g(r) and the structure factor S(q), obtained from the three approaches with good agreement. Thus, we used the validated MD simulations to calculate the microemulsion's dynamics properties that we discussed using the mean-squared displacement (MSD) and the diffusion coefficients. We found that the presence of moderate quantities of PEO-m, from 4 to 12 PEO-m per microemulsion, does not influence the microemulsion shape, increases the stability of the microemulsion, and slightly decrease the dynamics. Our in vitro and in silico results suggest that polymer incorporation, which has interesting in vivo implications, has no disadvantageous effects on the microemulsion properties.

Abstract
We studied a large range of identical spherical oil/water microemulsion (O/W-MI) volume fractions. The O/W-MIs are stabilized by cetylpyridinium chloride ionic surfactant (CpCl) and octanol cosurfactant and dispersed in salt water. We grafted different numbers of dodecyl–(polyEthylene oxide)227–dodecyl triblock copolymer that we note (n(D–PEO227–D)), where n varies from 0 to 12. We accomplished the grafting process by replacing a small amount of CpCl and octanol with the appropriate n(D–PEO227–D). The aim is to determine the interaction/structure relationship of the covered microemulsions. Precisely, we are interested in a quantitative investigation of the influence of volume fraction Φ, temperature (T), and n(D–PEO227–D) on the microemulsion sol/gel transition. To this end, we first study the uncoated microemulsion structure depending only on Φ. Second, we determine the coated microemulsions structure as a function of n(D–PEO227–D) for different Φ. Third, we examine the effect of temperature on the uncoated and coated microemulsion. We show that the sol/gel transition is controlled by the three main parameters, Φ, T, and n(D–PEO227–D). Accordingly, the uncoated microemulsion sol/gel transition, at ambient temperature, occurred for Φ ≃ 33.65%. By increasing Φ, the O/W-MIs show a glass state, which occurs, along with the gel state, at Φ ≃ 37% and arises clearly at Φ ≃ 60%. The coated O/W-MI sol/gel transition is found to be linearly dependent on n(D–PEO227–D) and takes place for Φ ≃ 26.5% for n(D–PEO227–D) = 12. Ordinarily, the decrease in temperature leads to gel formation of microemulsions for low Φ. Additionally, in this work, we found that the gelation temperature increases linearly with n(D–PEO227–D). Thus, the parameter n(D–PEO227–D) can control the sol/gel transition of the O/W-MIs at ambient temperature and moderate Φ. We studied the sol/gel transition of oil/water microemulsion (O/W-MI) covered with dodecyl–(polyEthylene oxide)227–dodecyl triblock copolymer.![]()

Abstract
AIM OF THE STUDY The main difficulties during retroperitoneal laparoscopic adrenalectomies are due to its location. Our objective was to define the relationship of the adrenals with the diaphragm and the psoas muscle. METHODS Our work is an anatomical dissection of 80 fresh cadavers' adrenals. To study the right adrenal, we performed a right nephrectomy and adrenal remained attached to the Inferior vena cava by its main vein. On the left, the edges of the adrenal have been identified by needles and the adrenal was reclined to study its projection on the posterior muscular wall. RESULTS The right adrenal is located higher, 13mm [4-20mm] above the medial arcuate ligament (MAL) in 16 cases (40%). Its lower border was at the same level as the MAL in 18 cases (45%) and 11mm [10-17mm] below the MAL in 6 cases (15%). The posterior support of the right adrenal was the right crus of the diaphragm (Right-CD) in 34 cases (85%) and straddling the Right-CD and the psoas in 6 cases (15%). The study of the relationships of the left adrenal with the MAL showed that the lower edge of the gland was at its same level in 16 cases (40%) and below in 24 cases (60%) by 14mm [8-24mm]. The posterior support of the left adrenal was the left crus of the diaphragm (Left-CD) in 16 cases (40%) and straddling the Left-CD and the psoas in 24 cases (60%). CONCLUSIONS Our results showed that the right adrenal is higher. The MAL is an important posterior element to the adrenal gland that could serve as an anatomical landmark to identify the adrenal during laparoscopic adrenalectomy.

Abstract
Molecular dynamics simulation (MD) is used to study the static and dynamic properties of positively charged decane/water microemulsions, for various volume fractions Φ (2.8%, 6.98%, 14%, and 26.5%). An effective hybrid potential combining three potentials, namely the hard-sphere repulsive potential, the van der Waals attractive potential, and the Yukawa repulsive potential, is used to describe the microemulsion interactions. The microemulsion shape is determined using the renormalized spectra in Porod representation. The appropriate potential parameters are tested using the Ornstein–Zernike integral equation approach with the Hypernetted Chain (HNC) closure relation by a comparison between the structure factor calculated from HNC and that obtained from Small Angle Neutron Scattering experiments (SANS). Thus, the micro arrangements of microemulsions have been analyzed using the pair correlation function g(r) and the structure factor S(q) obtained from HNC, SANS, and MD simulation using these parameters. The microemulsion dynamic properties were discussed using the mean-square displacement (MSD) and the diffusion coefficient Dc calculated from MD simulations. We report a molecular dynamics simulation using a proven effective interaction potential to study the physical properties of decane/water microemulsions.![]()

Abstract
Recent advancements in the use of microbial cells for scalable production of industrial enzymes encourage exploring new environments for efficient microbial cell factories (MCFs). Here, through a comparison study, ten newly sequenced Bacillus species, isolated from the Rabigh Harbor Lagoon on the Red Sea shoreline, were evaluated for their potential use as MCFs. Phylogenetic analysis of 40 representative genomes with phylogenetic relevance, including the ten Red Sea species, showed that the Red Sea species come from several colonization events and are not the result of a single colonization followed by speciation. Moreover, clustering reactions in reconstruct metabolic networks of these Bacillus species revealed that three metabolic clades do not fit the phylogenetic tree, a sign of convergent evolution of the metabolism of these species in response to special environmental adaptation. We further showed Red Sea strains Bacillus paralicheniformis (Bac48) and B. halosaccharovorans (Bac94) had twice as much secreted proteins than the model strain B. subtilis 168. Also, Bac94 was enriched with genes associated with the Tat and Sec protein secretion system and Bac48 has a hybrid PKS/NRPS cluster that is part of a horizontally transferred genomic region. These properties collectively hint towards the potential use of Red Sea Bacillus as efficient protein secreting microbial hosts, and that this characteristic of these strains may be a consequence of the unique ecological features of the isolation environment.

Abstract
INTRODUCTION Paragangliomas, defined as extra-adrenal chromaffin-cells tumors, are rarely located in the retro-peritoneum. Clinical presentation is similar to pheochromocytoma, and mainly depends on the producing character of the tumor. Positive diagnosis requires plasmatic and urinary hormonal assays. Radiological and isotopic explorations are essential before surgery. The only curative therapeutic strategy is surgical, associated to peri-operative prevention and monitoring of the frequently reported hemodynamic and cardiovascular disorders. Outcome depends of the metastatic character of the tumor, the presence of tumor remnant after surgical resection. Genetic study is recommended; the risk of recurrence and association to other neoplasm is more described in genetic forms. MATERIAL AND METHODS Authors report 5cases of retro-peritoneal paraganglioma, operated in the department of urology of Hospital, between 2013 and 2017. Observations are about 2men and 3women. Clinical presentation is not always specific and paraganglioma may be discovered fortuitously. Two patients have been operated by coelioscopic approach, midline incision was performed in two other cases, and dorsal lumbotomy associated to a Rutherford-Morrison incision in a patient. RESULTS Two patients presented resistant hypertension and palpitation associated to suspect retro-peritoneal masses in imagery and elevated urinary methoxylated derivates before surgery. One patient was asymptomatic and the tumor was discovered in imagery. Per-operative hypertensive crisis and sinus tachycardia occurred in a case. The average follow-up period is 22.8months. Hypertension and palpitation disappeared after surgery. There was no recurrence for all the operated patients. CONCLUSION Retro-peritoneal paraganglioma is a rare condition. Symptoms are not specific and clinical presentation may be similar to pheochromocytoma. Abdominal CT-scan and MRI, in association with MIBG scintigraphy are strongly evocative. Histological examination ensures diagnosis. Per-operative cardio-vascular disorders are to consider and must prevented and managed by anesthesiologists. Complete surgical resection is the only curative treatment and avoids recurrences.

Abstract
Background Splenogonadal fusion is a rare and benign condition. Diagnosis is challenging for clinicians. Despite its indolence, diagnosis is often confirmed after orchidectomy. Surgery is mandatory, particularly to rule out the extremely rare association with malignancy. Case presentation We report a case of splenogonadal fusion in a 38-year-old North African man presenting a palpable scrotal mass. We describe clinical aspects, pathogenic hypothesis, radiological features, as well as surgical management principles. Conclusions Splenogonadal fusion is rarely suspected and diagnosed preoperatively. A diagnosis is made once an ectopic testicular mass is associated with cryptorchidism and suggestive radiological signs. A better knowledge of the clinical and radiological features of splenogonadal fusion provides an opportunity for conservative surgery.

Abstract
Cutaneous metastases from bladder malignancies are rare. We report the case of a 74 year old man who underwent cysto-prostatectomy and adjuvant chemotherapy for a pT3b N+ bladder transitional cell carcinoma. Four months later, he presented with skin disseminated pigmented lesions. Skin biopsy confirmed cutaneous metastasis from urothelial carcinoma.
