Abstract
The specific changes in antral follicle numbers and wave-like development have remained unrevealed in cyclic ewes fed high-protein, high-energy lupin grain for 6 days during the luteal phase of the estrous cycle (i.e., short-term nutritional flushing). This study was mainly conducted to determine ovarian effects of the 6-day lupin grain feeding in non-prolific Polish Mountain ewes, using transrectal ovarian ultrasonography and abdominal videoendoscopy. Estrus and ovulations were synchronized in 24 ewes with progestin-releasing intravaginal sponges for 12 days during the middle portion of the breeding season (September-October; 50.0458°N, 19.8406°E). Twenty-four ewes were assigned to three equal groups (n=8 each), including the Control group being fed the maintenance diet (i.e., hay-only), Treatment 1 receiving 500 g of lupin grain once a day, and Treatment 2 receiving 250 g of lupin grain twice a day, from days 9-14 of the synchronized estrous cycle (day 0=first ovulation of the interovulatory period studied). No differences were observed in the mean ovulation rate among the three groups of Polish Mountain ewes (P>0.05). Ovarian antral follicles emerging in the penultimate wave of the estrous cycle in Treatment 2 ewes had a longer growth phase (p <0.05) and attained a greater diameter (p <0.05) before ovulation, in comparison to those in the other two groups. A final wave of the interovulatory interval emerged ~1 day earlier in Treatment 2 than in Treatment 1 ewes (p <0.05). Nutritional supplementation with lupin grain increased the number of 3-mm follicles in Treatment 2 ewes (p <0.05). The results of this study indicated that short-term nutritional flushing with lupin grain from mid- to late luteal phase did not consistently enhance ovulatory responses in non-prolific genotypes of ewes. Although the administration of lupins altered the timing of wave emergence, ovulatory follicle diameter, or duration of different stages of the follicular lifespan, it failed to increase the number of ovulatory follicles emerging in the penultimate and final waves of the estrous cycle in non-prolific Polish Mountain sheep.

Abstract
Economic potential of the swine industry hinges upon the reproductive performance of sows, which may be enhanced by improving uterine capacity, a component trait of litter size and piglet productivity. Previous attempts at characterising morphological traits indicative of high uterine volume have not been completely successful, resulting in the continued need for a reliable method of predicting reproductive value to improve production efficiency of the sow. Hence, the main objective of this study was to scrutinize macro- and micro-morphology of the sow’s reproductive tract for quantitative correlations with fertility indices. Reproductive records from Polish Landrace×Polish Large White sows (mean±s.e.m. parity: 4.3±0.6, range: 2–8) were used to examine the associations between fertility and ovarian/uterine morphology (n=34) or uterine histomorphometry (n=10) posthumously. Simple linear regression was performed to determine the relationship between anatomical or histological parameters and various measures of reproductive performance. Several measures related to the ovary, including right and left ovarian weight (r=0.50, P=0.005, and r=0.49, P=0.006, respectively), were positively correlated with the litter size, whereas left ovarian number of corpora lutea (r=−0.38, P=0.04) was negatively correlated with the mean litter size. Analysis of histomorphological characteristics of the uterine wall collected during the luteal phase of the oestrous cycle revealed correlations between mean litter size and myometrial vascular content (r=0.75, P=0.03), the proportion of myometrial stroma (r=−0.68, P=0.03), and the variability of endometrial thickness (r=−0.72, P=0.02) in sows. Eight ovarian, vaginal, and uterine characteristics were significantly correlated with mean lifetime numbers of live born and stillborn piglets/litter or the last litter size before slaughter. In conclusion, several anatomical and histomorphological metrics that relate to reproductive performance of swine may be used to inform production protocols and as a tool for selection of elite breeding sows, warranting future research into noninvasive or minimally invasive techniques for obtaining such measures.

Abstract
Why do quantum evolutions occur and why do they stop at certain points? In classical thermodynamics affinity was introduced to predict in which direction an irreversible process proceeds. In this paper the quantum mechanical counterpart of the classical affinity is found. It is shown that the quantum version of affinity can predict in which direction a process evolves. A new version of the second law of thermodynamics is derived through quantum affinity for energy-incoherent state interconversion under thermal operations. we will also see that the quantum affinity can be a good candidate to be responsible, as a force, for driving the flow and backflow of information in Markovian and non-Markovian evolutions. Finally we show that the rate of quantum coherence can be interpreted as the pure quantum mechanical contribution of the total thermodynamic force and flow. Thus it is seen that, from a thermodynamic point of view, any interaction from the outside with the system or any measurement on the system may be represented by a quantum affinity.

Abstract
The aim of this study was to determine the effects of morphine on the biomass and development rate of Chrysomya albiceps (Diptera: Calliphoridae). C. albiceps, a well-known forensically important species which is among the first wave of faunal succession on human cadavers, which makes it a valuable source of information for the estimation of postmortem interval (PMI). Antemortem exposure to substances such as drugs and toxins may have an effect on the biomass and/or on the development rate of insects that feed on carcass, which may directly affect PMI estimation. In this study, three rabbits were administered 12.5, 25 or 50 mg/ml of morphine sulfate via ear perfusion over a period of 3 hours, and a fourth rabbit, which did not receive morphine, was used as a control. The rabbits were sacrificed using chloroform 30 minutes after morphine administration. The tissues were analyzed for the presence of morphine using HPLC-UV. Morphine was detected in all tissues of rabbits that received morphine, except in the bile and spleen of the rabbit which received 12.5 mg/ml dose of morphine. The presence of morphine in rabbit tissues retarded larval development rate, but accelerated the puparial development rate. The rate of development of C. albiceps larvae that fed on rabbits which received 25 and 50 mg/ml dosages of morphine was 9 days each. However, the rate of larval development was similar in the 12.5 mg/ml morphine group and the control; 6 days. Results of this study show that an underestimation of the postmortem interval of 72 h based on larval development and an overestimation of 24 to 48 h based on puparial development is possible if the presence of morphine in tissues is not considered. Moreover, the decreased larval development rate caused an increase larval length and weight compared with the control group. In this study, we found a strong correlation between the concentration of morphine administered and concentrations in rabbit tissues. In the estimation of PMI, it is recommended that effects of drugs such as morphine on the development of carcass colonizers be considered.

Abstract
Mucormycosis is a devastating infection caused by Mucoralean fungi (Mucormycotina, Mucorales). Data concerning the global epidemiology of mucormycosis are scarce and little is known about the characteristics of mucormycosis in Iran. In this study, we aimed to understand the distribution of this infection in Iran retrospectively and to ascertain whether the patterns of infection are associated with specific host factors or not. A total of 208 cases were included in this study occurring during 2008-2014 and were validated according to (EORTC/MSG) criteria. A rising trend as significant increase from 9.7% in 2008 to 23.7% in 2014 was observed. The majority of patients were female (51.4%) with median age of 50 and the infections were seen mostly in autumn season (39.4%). Diabetes mellitus (75.4%) was the most common underlying condition and sinus involvement (86%) was the mostly affected site of infection. Amphotericin B (AmB) was the drug of choice for the majority of cases. Sixty four isolates did not show any growth in the lab and only 21 cases were evaluated by ITS sequencing, among them; Rhizopus arrhizus var. arrhizus was the dominant species. Considering the high mortality rate of mucormycosis, early and accurate diagnosis, with the aid of molecular methods may provide accurate treatments and improve the survival rate. Therefore, increased monitoring and awareness of this life-threatening disease is critical.

Abstract
BACKGROUND Onychomycosis is a common nail infection caused by dermatophytes, non-dermatophyte molds (NDM), and yeasts. Aspergillus species are emerging as increasing causes of toenail onychomycosis. The purpose of this study was species delineation of Aspergillus spp. isolated from patients with onychomycosis. METHODS During a period of one year (2012-2013), nail samples were collected from patients clinically suspected of onychomycosis and subjected to microscopic examination and culture. Species identification was performed based on macro- and micro-morphology of colonies. For precise species identification, PCR-amplification and sequencing of the beta-tubulin gene followed by BLAST queries were performed where required. RESULTS A total of 463/2,292 (20.2%) tested nails were diagnosed with onychomycosis. Among the positive specimens, 154 cases (33.2%) were identified as saprophytic NDM onychomycosis, 135 (29.2%) of which were attributable to Aspergillus. Aspergillus species isolated from the infected nails included Aspergillus flavus (77.3%, n=119), Aspergillus niger (n=4), Aspergillus tubingensis (n=4), Aspergillus terreus (n=3), Aspergillus sydowii (n=2), Aspergillus spp. (n=2), and Aspergillus candidus (n=1). Among the patients diagnosed with onychomycosis due to Aspergillus (average patient age, 47.4 years), 40 had fingernail and 95 toenail involvement. The large toenails were most commonly affected. CONCLUSIONS This study identified a markedly high occurrence of A. flavus, and this fungus appears to be an emerging cause of saprophytic onychomycosis in Iran. The study moreover highlights the necessity of differentiating between dermatophytic and non-dermatophytic nail infections for informed decisions on appropriate therapy.

Abstract
OBJECTIVE Dermatophytes are taxonomically classified in the genera Trichophyton, Microsporum, and Epidermophyton. Pleomorphism, cultural variability, slow growth and sporulation, and the need for additional physiological tests make dermatophytes notoriously difficult to identify. The present study aimed to compare the results of morphological and molecular identification of certain groups of clinical isolates of dermatophytes with a view to evaluating the accuracy of molecular methods. PATIENTS AND METHODS For each sample, the ITS1-5.8S-ITS2 rDNA region was amplified using the primers ITS1 and ITS4. PCR products were subjected to restriction fragment length polymorphism (RFLP) analysis using the enzyme MvaI and isolate identification was performed by comparing the electrophoretic RFLP patterns with reference profiles obtained previously. Finally, paired comparative analyses of molecular and conventional methods were performed. RESULTS While morphology results from routine daily reports of the laboratories indicated that 18 (6.8%) and 136 (52.10%) of the isolates were T. rubrum and T. interdigitale, respectively, PCR-RFLP results suggested that T. rubrum was the most common etiological agent of ringworm accounting for 94 (36.01%), followed by T. interdigitale accounting for 71 (27.20%). Interestingly, 80.8% out of the 94 isolates identified as T. rubrum by molecular testing had been identified by morphological examination as belonging to different species, such as T. interdigitale (75.5%), E. floccosum (2.1%) and M. canis, T. verrucosum, and T. tonsurans (each 1.06%). Ten strains out of 261 (T. interdigitale, n=8; E. floccosum, n=2) had been defined as unknown species by morphological tests. CONCLUSION An unexpected high percent of isolates identified as T. interdigitale by conventional methods were in effect T. rubrum shown by PCR-RFLP, and regarding the necessity of correct identification of dermatophytes recovered from different clinical forms of the infection, we highly recommend ITS-sequencing or ITS-RFLP of the isolates, particularly for epidemiological research studies.

Abstract
BACKGROUND Residents play an important role in the delivery of hospital care. They regularly work overnight, in emergency situations and with workload and stress which can affect their performance and quality of working life (QWL). This study explores the QWL and its contributory factors in residents working at hospitals affiliated with Tehran University of Medical Sciences (TUMS), Tehran, Iran. METHODS Medline was searched to identify questionnaires for measuring QWL in healthcare professionals and these questionnaires were used to design a comprehensive questionnaire for measuring residents QWL. Face and content validity of the questionnaire were examined by 7 experts. The questionnaire then was completed twice with one-week interval by 14 residents to assess the intera-rater reliability. Then 310 questionnaires were distributed among residents working at different specialties in 7 hospitals affiliated to TUMS including a large general hospital, two medium general hospitals and four small single specialty hospitals. Statistical analyses were performed by SPSS. RESULTS Totally, 263 residents (84%) completed the questionnaire. The quality of working life was very well in 18%, well in 32%, moderate in 31%, low in 14% and very low in 5% of residents. Pediatric residents had the highest and urology and internal medicine residents had the lowest quality of working life. CONCLUSION The QWL is high in the majority of residents, but the QWL is still not desirable in a significant proportion of them. The questionnaire used in this study is reliable and valid. The residents' QWL still need improvement.

Abstract
OBJECTIVES Changes in gender ratio generally reflect differences in mortality rates in men and women. Female mortality rates, on the other hand, can be used as an index of the trends in women's health. This study looks at the trend in the population gender ratio from 1956 to 2006, with a focus on analysing mortality rates and hence the overall health of Iranian women over the last 50 years. STUDY DESIGN Cohort-type analysis using data from the last five population censuses in Iran. METHODS Data were used to calculate gender ratios and analyse their trends over the 50-year period from 1956 to 2006. RESULTS According to the 1956 Census, there were 98 men for every 100 women in the 25-34 years age group (male:female ratio=0.98). In the next census, conducted 10 years later (1966), the gender ratio increased to 121 in the 39-44 years age group. The discrepancy increased in later censuses; this trend indicates that mortality in the 25-34 years age group was significantly higher in 1956-1966 compared with subsequent decades. The social and economic crises of the 1940s probably left women of reproductive age exceptionally vulnerable to a wide range of adverse health outcomes. The fact that the trend ceased in 1976 with no further increase in the gender ratio may be due to improving social conditions and greater effectiveness of healthcare programmes directed at women. CONCLUSION As life expectancy is calculated on the basis of the conditional probability of death over specific intervals, the apparent discrepancy between the current gender ratios and life expectancy data may be due to higher female death rates before 1976.

Abstract
Habitual dislocation of the hip occurred in a nine-year-old girl. The nomenclature of the literature on this disorder and other related conditions is confusing. The following simple classification is therefore proposed: (1) recurrent dislocation (posttraumatic, nonvoluntary); (2) voluntary dislocation (nonhabitual, associated with ligamentous laxity or paralytic disease); (3) habitual dislocation (not associated with significant ligamentous laxity). The treatment significantly differs in each of the described conditions. The diagnosis of habitual dislocation precludes correct interpretation of the history and physical examination.

Abstract
Three different distraction devices were investigated for the treatment of leg-length discrepancy caused by poliomyelitis in 144 patients. The average leg-length discrepancy was 5.2 cm and lengthening obtained 4.8 cm. For tibial leg-lengthening. Anderson's apparatus was used in 50 patients; an external fixator device (developed in Shafa Rehabilitation Hospital) was used in 40 patients; and the Wagner apparatus was used in 51 patients. The incidence of major complications was low in all 3 groups. The overall failure rate was 4%. There were no significant differences in the final results among the 3 groups. However, preference is given to the Wagner device because of its practical advantages.

Abstract
This is a report of 5 cases of congenital pseudarthrosis of the clavicle, a rare disorder of the shoulder girdle. Little more than 100 cases have been reported in the literature; 3 of our 5 cases represent a very rare form of left side involvement with dextrocardia. The pseudarthrosis mass generally protrudes under the skin and may need surgical correction. When unilateral, there is marked and unexplained predominance for the right side. Three cases required no treatment; 2 were successfully treated by excision of the bone ends, bone grafting and internal fixation.
