5% accuracy. The current work integrates genotypic, 3D structural modeling and phenotypic characteristics of CDG-SRD5A3 cases with the successful development of computer tool for accurate facial recognition of CDG-SRD5A3 complex cases to assist in the diagnosis of this particular disorder globally.
Dermatofibroma, also known as cutaneous benign fibrous histiocytoma, is a common skin tumour.

The aim of this paper was to present a rare variant of dermatofibroma, atrophic dermatofibroma, emphasizing histopathological and dermoscopic features.

A case of atrophic dermatofibroma in a female patient with the characteristic histopathological features and newly demonstrated dermoscopic findings is presented.

A 54-year-old female presented with a depressed reddish lesion on the back showing histopathological findings of atrophic dermatofibroma. The dermoscopy of the lesion revealed a peripheral pigment network surrounding a pink-reddish colouration around a central whitish scar-like patch with white-yellow scales which was not an exact match with the description in the literature.

Atrophic dermatofibroma is a rare variant that presents as an atrophic, depressed skin lesion which can easily be overlooked. Atrophic dermatofibroma should be considered in the differential diagnoses of atrophic, depressed lesions on the upper body of middle-aged women. The case of atrophic dermatofibroma presented here showed typical histopathologic findings with atypical dermoscopic features.

To describe the natural history, reconstructive solutions, and functional outcomes of those men undergoing pubectomy and urinary reconstruction after prostate cancer treatment.

This study retrospectively identified 25 patients with a diagnosis of urosymphyseal fistula (UF) following prostate cancer therapy who were treated with urinary reconstruction with pubectomy. This study describes the natural history, reconstructive solutions, and functional outcomes of this cohort.

All 25 patients had a history of pelvic radiotherapy for prostate cancer. The median (interquartile range [IQR]) time from prostate cancer treatment to diagnosis of UF was 11(6, 16.5)years. The vast majority of men (24/25; 96%) presented with debilitating groin pain during ambulation. RG2833 Posterior urethral stenosis was common (20/25; 80%), with 60% having repetitive endoscopic treatments. Culture of pubic bone specimens demonstrated active infection in 80%. Discordance between preoperative urine and intraoperative bone cultures was common, 21/22 (95.5%). After surgery, major 90-day complications (Clavien-Dindo Grade III and IV) occurred in eight (32%) patients. Pain was significantly improved, with resolution of pain (24/25; 96%) and restoration of function, the median (IQR) preoperative Eastern Cooperative Oncology Group Performance Status (ECOG PS) was 3 (2, 3) vs median postoperative ECOG PS score of 0 (0, 1).

Endoscopic urethral manipulation after radiation for prostate cancer is a risk factor for UF. Conservative management will not provide symptom resolution. Fistula decompression, bone resection, and urinary reconstruction effectively treats chronic infection, improves pain and ECOG PS scores.

Their auxetic behaviors emerge from periodic cellular structures regardless of the materials used. The majority of such metamaterials are constructed by top-down approaches and macroscopic with unit cells of microns or larger. There are also molecular auxetics including natural crystals which are not designable. There is a gap from few nanometers to microns, which may be filled by biomolecular self-assembly. Herein, we demonstrate two-dimensional auxetic nanostructures using DNA origami. Structural reconfigurations are performed by two-step DNA reactions and complemented by mechanical deformation studies using molecular dynamics simulations. We find that the auxetic behaviors are mostly defined by geometrical designs, yet the properties of the materials also play an important role. From elasticity theory, we introduce design principles for auxetic DNA metamaterials.
The present study aimed to explore the need for information about permanent contraception in Japanese women with repeated cesarean sections (CS).

The present, cross-sectional survey used a self-administered questionnaire mailed to women with a second or later CS at Tokyo Metropolitan Tama Medical Center between March 2010 and December 2017. Those who were pregnant, had given birth less than 1 year before the survey or had an hysterectomy were excluded.

The present study analyzed 284 patients (60 with permanent contraception, 224 without permanent contraception). Forty-eight (80%) of women with permanent contraception, and 135 (60%) of women without permanent contraception believed that information on permanent contraception was needed before CS. Among women without permanent contraception, significantly fewer women obtained adequate information of permanent contraception from their healthcare workers before a CS compared with women with permanent contraception (8% vs. 71%, p < 0.001). A higher rate of unreliable contraceptive use (41%) and unintended pregnancies (4%) after the latest CS were found among the women without permanent contraception.

A large portion of the study cohort wished they had received information on permanent contraception before CS; however, the patients without permanent contraception had limited access to this information. Adequate information about permanent contraception should be provided to women planning a CS to enable them to make an informed decision with respect to the treatment.

In order to explore the effect of alkyl groups and substituents attached to aromatic ring on the chemical shifts, 63 title compounds were synthesized. Their 1 H NMR and 13 C NMR spectra were obtained; and the effects of the alkyl chain length and substituents on the chemical shifts (δH (CHN), δC (CHN), δH (OH), and δC (COH)) were studied. The results show that (1) the alkyl polarizability effect index (PEI) has an important influence on the chemical shifts of the above four atoms, with the increase of PEI, the values of δH (CHN) and δc(CHN) decrease, and the values of δH (OH) and δC (COH) increase. (2) The influence of substituent X attached to aromatic ring on the chemical shift is related to its position by taking OH or CHN as reference. As for the effect of substituent on the chemical shifts, the effect of Hammett constant σ(X)OH and excited-state substituent parameter σ CC ex X  OH with OH as reference are different from that ofσ(X)CHN and σ CC ex X  CH  N with CHN as reference, and there is a "homoring competition effect" of the substituent. (3) The effect of the cross-interaction between X and OH on the chemical shift is also significantly different due to the different position of X. Quantitative correlation equations against chemical shifts were built for the four atoms, and the stability and prediction ability of the obtained equations were confirmed by leave-one-out cross validation.
Artificial rupture of the amniotic membranes during the labor, which is called amniotomy, is a common procedure in modern obstetric and midwifery protocols. There is no definite agreement regarding the timing of amniotomy in a delayed labor. In this study, we have discussed the history of amniotomy in medieval Persia mentioning the Persian medicine recommendations in this regard.

We studied main Persian medicine textbooks such as Canon of Medicine by Avicenna to investigate the history of labor management and amniotomy indications. In addition, amniotomy in current literature was studied using PubMed and Google Scholar databases.

Persian medicine has recommended artificial rupture of membranes for labor augmentation based on its own theories. Methods for facilitation of the labor have been divided into two groups one group before and the other during the labor. Avicenna has carefully explained the indication of amniotomy. He has recommended artificial rupture of membranes in cases of intact membranes with cervical dilatation and fetal descent. A needle or a kind of surgical knife called Mabzaa had been introduced for this procedure.

It seems that Iranian physicians are the first scholars who have introduced the amniotomy for labor management in the 11th century. Persian medicine recommendations for labor facilitation should be considered in future studies.

Forty-one participants with type 2 diabetes undergoing HD were recruited. The overall mean absolute relative difference and mean absolute difference were 23.4% and 33.9 mg/dL, respectively. Sensor glucose levels and capillary glucose levels were significantly correlated (r = 0.858, P  less then  .01), although the sensor glucose levels were significantly lower than the capillary glucose levels. The accuracy of FreeStyle Libre in patients undergoing HD became deteriorated with the days of usage. The percentage of sensor results in Zones A and B in the consensus error grid analysis and in the Clarke error grid analysis were 99.7% and 99.0%, respectively. Its insufficient accuracy necessitates adjunct usage of FreeStyle Libre with self-monitoring of blood glucose in patients undergoing HD.This study hypothesizes that melatonin with exogenous progesterone (CIDR) can improve follicular, luteal, ovarian and uterine haemodynamic of heat-stressed cows. Holstein cows (N = 12) studied for two spontaneous oestrous cycles during winter then divided equally during summer into the CIDR group received CIDR for 7 days and the melatonin group (Mel) received three injections of melatonin (75 mg/head) at the CIDR insertion, removal and ovulation days. Blood samples were collected to assay oestradiol (E2), progesterone (P4) and nitric oxide (NO). On day 0 (Ovulation), Mel had more small follicles (p less then .05), higher ipsilateral and contralateral ovarian arteries (Ov.A.) peak systolic velocity (PSV), higher ipsilateral uterine artery (Ut.A.) PSV (p = .031) and blood flow volume (BFV), also Mel elevated contralateral Ut.A. PSV and BFV (p less then .0001) but lowered contra Ut.A. pulsatility index (PI, p less then .0001), E2 (p less then .01) and NO (p less then .0001). Mel increased the corpus luteum diameter (CL, p less then .
