Purpose: In patients with erectile dysfunction, it is important to differentiate psychogenic from organic causes. Penile Doppler ultrasonography is a relatively inexpensive and minimally invasive tool for this purpose. This study was conducted to evaluate the causes of erectile dysfunction in an adult male population, using penile Doppler ultrasonography.Materials and Methods: A retrospective study was conducted in a single center. All patients who presented with complaints of erectile dysfunction and underwent penile Doppler ultrasonography between July 2014 and June 2016 were included in this study. All examinations were performed using GE Voluson S6 and GE Logiq P5 devices. Following baseline scans, an intracavernosal injection of 20 μg of prostaglandin E1 was given. Peak systolic and end diastolic velocities were measured in each cavernosal artery. Patients with a peak systolic velocity of <25 cm/s were considered to have arterial insufficiency, while an end diastolic velocity of >5 cm/s was considered to indicate venous incompetence.Results: Out of 97 patients (mean age, 37.09±11.59 years; range, 19∼69 years), 50 patients (51.5%) had normal findings, 24 patients (24.7%) had arterial insufficiency, 15 patients (15.5%) had a venous leak, and 8 patients (8.2%) patients had arterial insufficiency with a venous leak. Psychogenic erectile dysfunction was significantly higher among patients aged ≤40 years, while arterial insufficiency with or without a venous leak was significantly higher among patients aged >40 years (p=0.022).Conclusions: A majority of the studied individuals demonstrated no organic cause of erectile dysfunction, thus confirming a high prevalence of the psychogenic etiology, particularly in relatively young individuals.

Regulation of cuticular wax biosynthesis in plants under abiotic stress
Md Shaheenuzzamn,Shandang Shi,Kamran Sohail,Hongqi Wu,Tianxiang Liu,Peipei An,Zhonghua Wang,Mirza Hasanuzzaman 한국식물생명공학회 2021 Plant biotechnology reports Vol.15 No.1
Cuticular waxes are the covering of the outer layer of the plant, consist of hydrocarbon appears like whitish flm or bloom in plant organs. They play a vital role like a safeguard from diferent stress condition in the plant. Since environmental factors are active regulators of cuticular wax biosynthesis, composition, quantity, and deposition, it is evident that cuticular wax is associated with plant stress responses. The diversity of cuticular wax compositions is a proof of the wealth of genes associated in plant wax production. Moreover, a number of wax genes were distinguished in plant/crops at abiotic stress conditions but, regulation of control of those wax genes has not been studied very well in major crop plants at abiotic conditions. A very few transcriptions factors were identifed to regulate the expression level of wax genes of cuticular wax biosynthesis at abiotic stress condition. However, further study is needed to identify more candidate transcriptional regulation factors to cuticular wax production in diferent crop plants in diverse abiotic environments. Therefore, regulation of cuticular wax production under diverse abiotic stresses and the role of transcription factors into the plant cuticular wax accumulation will be helpful to engineer crop plants and improve transgenic crops for stress tolerance. In this review, we focused on a new perspective on transcriptional factors to regulate functional genes of cuticular wax biosynthesis in plants at abiotic stresses.

Background: The Pakistan Atomic Energy Commission Cancer Registry (PAECCR) program has made availability of a common cancer incidence database possible in Pakistan. The cancer incidence data from nuclear medicine and oncology institutes were gathered and presented. Materials and Methods: The cancer incidence data for the last 30 years (1984-2014) are included to describe a data set of male and female patients. The data analysis concerning occurrence, trends of common cancers in male and female patients, stage-wise distribution, and mortality/follow-up cases is also incorporated for the last 10 years (2004-2014). Results: The total population of provincial capital Lahore is 9,800,000. The total number of cancer cases was 80,390 (males 32,156, females 48,134). The crude incidence rates in PAECCR areas were 580.8/$10^5$ during 2010 to 885.4/$10^5$ in 2014 (males 354.1/$10^5$, females 530.1/$10^5$). The cancer incidence rates for head and neck (15.70%), brain tumors (10.5%), and non-Hodgkin lymphoma (NHL, 9.53%) were found to be the highest in male patients, whereas breast cancer (46.7%), ovary tumors (6.80%), and cervix (6.31%) cancer incidence rates were observed to be the most common in female patients. The age range distribution of diagnosed and treated patients in conjunction with the percentage contribution of cancer patients from 15 different cities of Punjab province treated at the Institute of Nuclear Medicine and Oncology, Lahore are also included. Leukemia was found to be the most common cancer for the age group of 1-12 years. It has been identified that the maximum number of diagnosed cases were found in the age range of 51-60 years for males and 41-50 years for female cancer patients. Conclusions: Overall cancer incidence of the thirty years demonstrated that head and neck and breast cancers in males and in females respectively are the most common cancers in Punjab province in Pakistan, at rates almost the highest in Asia, requiring especial attention. The incidence of brain, NHL, and prostate cancers among males and ovarian and cervix cancers among females have increased rapidly. These data from a major population of Punjab province should be helpful for implementation of appropriate planning, prevention and cancer control measures and for determination of risk factors within the country.
