Abstract
OBJECTIVE This study aimed to compare the efficacy and safety of oral and transdermal estradiol in alleviating menopausal symptoms. METHOD A total of 257 recently menopausal women were randomized into two groups. The t-E2 group received transdermal estradiol (2.5 g per day) (n = 128) and the o-E2V group received oral estradiol valerate (2 mg per day) (n = 129) for 24 weeks; both groups received micronized progesterone (200 mg per day). The primary outcome measure is the change in the modified Kupperman Menopausal Index (KMI) after 24 weeks of treatment. Menopausal symptoms were recorded at screening and at 4, 12 and 24 weeks using both the KMI and the Menopause Rating Scale (MRS). RESULTS Significant amelioration was observed by KMI and MRS scores for both groups after treatment (p < 0.001). The mean KMI scores showed no difference between the two groups. The mean MRS scores were similar between the two groups at baseline and after 4 weeks of treatment. The results showed statistical differences after 12 weeks and 24 weeks of treatment (p = 0.005 and p = 0.011). Both the after-treatment scores minus the baseline scores of KMI and MRS and the incidence of adverse effects showed no difference between the two groups. CONCLUSIONS This study shows that both transdermal and oral estradiol are effective in relieving menopausal symptoms, with little difference in treatment efficacy and safety. CLINICAL TRIAL NUMBER ChiCTR2300073146.

Abstract
Sirtiun 5 (SIRT5) is a NAD+-dependent protein lysine deacylase. It is emerging as a promising target for the development of drugs to treat cancer and metabolism-related diseases. In this study, we screened 5000 compounds and identified a hit compound 14 bearing a pyrazolone functional group as a novel SIRT5-selective inhibitor. Structure-based optimization of 14 resulted in compound 47 with an IC50 value of 0.21 ± 0.02 μM and a 100-fold improved potency. Compound 47 showed substantial selectivity for SIRT5 over SIRT1-3 and SIRT6. Biochemical studies suggest that 47 does not occupy the NAD + -binding pocket and acts as a substrate-competitive inhibitor. The identified potent and selective SIRT5 inhibitors allow further studies as research tools and therapeutic agents.

Abstract
UNLABELLED Enduring sustainability challenges requires a new model of collective leadership that embraces critical reflection, inclusivity and care. Leadership collectives can support a move in academia from metrics to merits, from a focus on career to care, and enact a shift from disciplinary to inter- and trans-disciplinary research. Academic organisations need to reorient their training programs, work ethics and reward systems to encourage collective excellence and to allow space for future leaders to develop and enact a radically re-imagined vision of how to lead as a collective with care for people and the planet.

Abstract
Whether seeds germinate or maintain dormancy is decided upon through very intricate physiological processes. Correct timing of these processes is most important for the plants life cycle. If moist conditions are encountered, a low dormancy level causes pre-harvest sprouting in various crop species, such as wheat, corn and rice, this decreases crop yield and negatively impacts downstream industrial processing. In contrast, a deep level of seed dormancy prevents normal germination even under favourable conditions, resulting in a low emergence rate during agricultural production. Therefore, an optimal seed dormancy level is valuable for modern mechanised agricultural systems. Over the past several years, numerous studies have demonstrated that diverse endogenous and environmental factors regulate the balance between dormancy and germination, such as light, temperature, water status and bacteria in soil, and phytohormones such as ABA (abscisic acid) and GA (gibberellic acid). In this updated review, we highlight recent advances regarding the molecular mechanisms underlying regulation of seed dormancy and germination processes, including the external environmental and internal hormonal cues, and primarily focusing on the staple crop species. Furthermore, future challenges and research directions for developing a full understanding of crop seed dormancy and germination are also discussed.

Abstract
Common bunt is one of the most important destructive diseases of wheat worldwide and is a domestic quarantined disease in China. However, a rapid and efficient method to identify the corresponding pathogens is currently limited. The objective of the present study was to develop a diagnostic molecular marker specific towards Tilletia foetida (Wall) Liro, a causal agent of the bunt disease. One specific DNA fragment for T. foetida (286 bp in length) was amplified using an Amplified Fragment Length Polymorphism (AFLP) assay and, this fragment was cloned and sequenced. One pair of specific primers (SC(286-1)/SC(286-2)), which was designed according to the sequence, could specifically amplify the corresponding fragment in all of the T. foetida isolates employed from both the People's Republic of China and United States, whereas this fragment could not be amplified by the other fungal species tested. Therefore, a specific Sequence Characterized Amplified Region (SCAR) marker was developed. This SCAR marker could distinguish T. foetida from related pathogenic fungi efficiently and could be used for the early diagnosis of the common bunt of wheat in the field, and provide an efficient way for disease surveillance and disease forecasting in cereal crop.

Abstract
Stripe rust, caused by Puccinia striiormis Westend f. sp. tritici, is one of the most important foliar diseases of wheat (Triticum aestivum L.) worldwide. Stripe rust resistance genes Yr27, Yr31, YrSp, YrV23, and YrCN19 on chromosome 2BS confer resistance to some or all Chinese P. striiormis f. sp. tritici races CYR31, CYR32, SY11-4, and SY11-14 in the greenhouse. To screen microsatellite (SSR) markers linked with YrCN19, F1, F2, and F3 populations derived from cross Ch377/CN19 were screened with race CYR32 and 35 SSR primer pairs. Linkage analysis indicated that the single dominant gene YrCN19 in cultivar CN19 was linked with SSR markers Xgwm410, Xgwm374, Xwmc477, and Xgwm382 on chromosome 2BS with genetic distances of 0.3, 7.9, 12.3, and 21.2 cM, respectively. Crosses of CN19 with wheat lines carrying other genes on chromosome 2B showed that all were located at different loci. YrCN19 is thus different from the other reported Yr genes in chromosomal location and resistance response and was therefore named Yr41. Prospects and strategies of using Yr41 and other Yr genes in wheat improvement for stripe rust resistance are discussed.

Abstract
In order to investigate the relationship between abnormal intracellular signal transduction and tumorgenesis of human pituitary somatotrophinomas, the effects of protein kinase A (PKA)-dependent growth hormone (GH) releasing hormone (GHRH) and protein kinase C (PKC)-dependent GH-releasing peptide (GHRP-6) on cAMP production were observed by using cell culture and biochemical methods, and the expression of the gsp oncogene was detected by using PCR and direct sequence assay methods in 11 patients with human pituitary somatotrophinomas. It was found that GHRP-6 exerted significant stimulatory effect on cAMP production by 2 gsp-positive tumors and no effect on the gsp-negative tumors. GHRP-6 could enhance the stimulation of cAMP production induced by GHRH in tumor without gsp oncogenes. It was suggested that both GHRH and GHRP-6 exert identical effects on human pituitary soamtotrophinomas, which was contributed to the cross-talk between the two intracellular signal transduction pathways in pituitary cells.

Abstract
Computerized physician order entry (CPOE) has been shown to improve quality, and to reduce resource utilization, but most available data suggest that it takes longer to enter orders using CPOE. We had previously implemented a CPOE system, and elected to evaluate its impact on physician time in the new setting. To do this, we performed a prospective study using random reminder methodology. Key findings were that interns spent 9.0% of their time ordering with CPOE, compared to 2.1% before, although CPOE saved them an additional 2% of time, so that the net difference was 5% of their total time. However, this is counterbalanced by decreased time for other personnel such as nursing and pharmacy, and by the quality and efficiency changes. We conclude that while CPOE has many benefits, it represents a major process change, and organizations must factor this in when they implement it.

Abstract
BACKGROUND Clinically, the severity of uremia is known to be inversely proportional to sexual desire and activity in patients with chronic renal failure. We studied sexual function and sex hormones in male patients with symptomatic hyperparathyroidism before and 3 months after parathyroidectomy. STUDY DESIGN From October 1998 to December 2000, 20 male patients with symptomatic secondary hyperparathyroidism were enrolled in this study. They underwent total parathyridectomy and autotransplantation of 90 mg of tissue to the subcutaneous tissue of the forearm or thigh. They all had regular sexual partners and were sexually active. Preoperatively, hemoglobin, hematocrit, calcium, phosphorus, alkaline phosphatase, intact parathyroid hormone (iPTH), prolactin, testosterone, leutenizing hormone (LH), and follicle stimulation hormone (FSH) were checked routinely. Three months after operation those data were checked again. Sexual function was evaluated with the International Index of Erectile Function (IIEF). Monthly frequency of attempted sexual intercourse, satisfaction of attempted intercourse, and enjoyment of intercourse were individually analyzed preoperatively and 3 months postoperatively. RESULTS Hemoglobin, hematocrit, testosterone, and LH were noted to have not significantly changed 3 months after surgery. Serum levels of calcium, phosphorus, alkaline phosphatase, FSH, and iPTH were significantly reduced, as were the levels of prolactin. But preoperative and postoperative FSH levels were within normal limits, and 70% of the postoperative alkaline phosphatase levels were above normal. Sexual function increased significantly 3 months after parathyroidectomy, as did monthly frequency of attempted intercourse, satisfaction of attempted intercourse, and enjoyment of intercourse. CONCLUSIONS Sexual function of male patients with symptomatic hyperparathyroidism can possibly be improved by parathyroidectomy and autotransplantation. Decreases in the levels of prolactin, calcium, phosphorus, and iPTH are also noticed after parathyroidectomy.

Abstract
PURPOSE Management of impalpable gonads in intersex patients remains a challenging problem. Since laparoscopic gonadectomy or gonadal preservation has been used in the management of impalpable gonads in the normal male population, laparoscopy can be an alternative method in the treatment of intersex patients. MATERIALS AND METHODS Laparoscopic operations were performed on 6 patients with intersex conditions, including the testicular feminization syndrome in 2, 17 beta-hydroxysteroid dehydrogenase deficiency in 1, 5 alpha-reductase deficiency in 1 and mixed gonadal dysgenesis in 2. RESULTS Laparoscopic gonadal biopsy, gonadectomy and hysterosalpingectomy were done in select patients. CONCLUSIONS Although the initial diagnoses were made by phenotypic presentation, and biochemical and cytogenetic studies, laparoscopy had an important role in defining the internal ductal and gonadal structures to confirm the diagnosis, and served as an efficient method for gonadectomy and removing structures contrary to the assigned gender.

Abstract
The in vitro susceptibility of Haemophilus influenzae type b to rifampin, cefotaxime, ceftazidime, ceftriaxone and cefuroxime was examined at inocula of 10(5) and 10(7) CFU/ml. Time-kill curves were then obtained using antibiotic concentrations at one-half the MIC for each drug at the two inocula with combinations of rifampin plus each of the cephalosporins. There was a pronounced inoculum effect with all of the cephalosporins except for cefuroxime, but the MIC values were also higher for the latter drug. The rare failure of some cephalosporins to promptly sterilize the cerebrospinal fluid in meningitis should encourage investigation of the relationship between the inoculum effect, minimum bactericidal concentration and cerebrospinal fluid antibiotic levels in these clinical situations. A marked synergistic effect was noted for most of the isolates, and therefore, cephalosporin-rifampin combinations might show clinical utility.

Abstract
Seven children with advanced neuroblastoma were treated with maturation therapy. This therapy consisted of 12 hours drip infusion of papaverine (40-45 mg/kg/day) for 2 days with or without high dose cyclophosphamide (2,000-3,600 mg/m2). During maturation therapy all patients received intravenous hyperalimentation. One patient who had received papaverine alone did not respond to the therapy. Among 6 patients treated with papaverine and high dose cyclophosphamide, 3 responded to the therapy, 2 did not and one died soon after the therapy. However, similar responses were obtained in 2 of 3 responders with high dose cyclophosphamide alone. After all, papaverine infusion was evaluated to be effective only in one patient. The clinically severe complications of papaverine infusion were somnolence in all patients and extrapyramidal symptoms in 6 patients. Because of these extremely high toxicity rates with little evidence of therapeutic effect, selection for this therapy should be carefully done and the treatment plan should be reconsidered.
