ABSTRACT
Macular amyloidosis (MA) is a skin condition with predominance in young women. We aimed to evaluate quality of life (QoL) and psychopathologies in these patients. In this cross-sectional study, patients with MA referring to the Imam Reza Hospital, Mashhad during 20182020, and their matched controls were included. Participants completed the 36-item short form survey (SF-36), the revised symptom checklist-90 (SCL-90-R), and the dermatology life quality index (DLQI). Overall, 40 women with a mean age of 36.80±10.19 years were studied. In the MA group, the SF-36 score was lower (P<0.001), and the SCL-90-R score was higher (P<0.001). The DLQI score was correlated with age (r=0.447; P=0.048) and pruritus severity (r=0.776; P<0.001), and was lower in patients with uncovered lesions (P=0.005). MA was associated with impaired QoL, which was determined by pruritus severity and lesion location; these patients can benefit from psychiatric interventions in this regard (AU)
La amiloidosis macular (AM) es una situación cutánea con predominancia en mujeres jóvenes. Nuestro objetivo fue evaluar la calidad de vida (QoL) y las psicopatologías en estos pacientes. En este estudio transversal se incluyó a pacientes con AM derivados al Hospital Imam Reza, de Mashhad, de 2018 a 2020, así como a sus controles pareados. Los participantes completaron la encuesta SF-36 (formulario breve de 36 ítems), el test de los 90 síntomas revisado (SCL-90-R) y el índice de calidad de vida en dermatología (DLQI). A nivel global, se estudió a 40 mujeres con una edad media de 36,80±10,19 años. En el grupo AM, la puntuación SF-36 fue más baja (p<0,001), siendo más alta la puntuación SCL-90-R (p<0,001). La puntuación DLQI se correlacionó con la edad (r=0,447; p=0,048) y con la severidad del prurito (r=0,776; p<0,001), siendo más baja en las pacientes con lesiones sin cubrir (p=0,005). La AM estuvo asociada a un deterioro de la QoL, que vino determinada por la severidad del prurito y la localización de la lesión. A este respecto, dichas pacientes pueden beneficiarse de intervenciones psiquiátricas (AU)

Present study was designed to compare the potential effects of high serum levels of LDL and oxidised LDL (OxLDL) on spermatogenesis parameters in male Wistar rats. Animals were allocated into three groups and were fed for 14 weeks with normal, cholesterol-rich and oxidised cholesterol-rich diets. Blood lipid profile, sex hormones level, as well as sex organs weight were evaluated. The sex organs weight in oxidised cholesterol-fed group was significantly reduced (P < 0.05). Spermatozoa count in the group with high serum concentration of OxLDL (64 ± 4.2 × 10(6) ) was markedly lower (P < 0.01) than that of normal rats (87 ± 4.1 × 10(6) ) and rats with high serum level of LDL (90 ± 6.3 × 10(6) ). Similarly, the percentage of viable spermatozoa was significantly (P < 0.001) decreased from 78% to 52% by high level of OxLDL in serum. While, nonoxidised LDL did not have suppressive effects on spermatogenesis and organs weight. Consistent with these effects, the serum concentration of sex hormones including FSH (P < 0.001), LH (P < 0.001) and testosterone (P < 0.01) was significantly decreased only in rats with high level of OxLDL but not in rats with high level of nonoxidised LDL. In conclusion, high OxLDL level showed higher destructive effect on reproductive system compared to the high LDL level.

Notable discussions have been developed over the distinctive effects of LDL and oxidized LDL (OxLDL) on myocardial functions. The aim of the present study was to investigate the effects of OxLDL on electrocardiogram and hemodynamic parameters of rat's heart in isoproterenol (ISO)-induced myocardial infarction (MI) model.Male Wistar rats were allocated in to 6 groups and receive one of the 3 formulated diets (standard, cholesterol-rich and oxidized cholesterol-rich diets). After 14 weeks to induce MI, rats in 3 groups were received ISO (100 mg/kg) for 2 consecutive days subcutaneously. Lipid profiles, electrocardiogram patterns and hemodynamic parameters of all groups were investigated.Serum levels of LDL, cholesterol and triglycerides were significantly higher in the fat-rich diet fed groups compared to control group (P<0.001). The ISO-treated rats showed a marked reduction in the R-amplitude, R-R interval, LVSP, left ventricular contractility (LVdP/dtmax) and relaxation (LVdP/dtmin) as well as severe elevation in ST-segment and LVEDP value compared to the respective normal rats. High serum level of OxLDL resulted in significant exacerbation in the destructive effects of ISO on R-amplitude, R-R interval, LVSP, left ventricular contractility (LVdP/dtmax), relaxation (LVdP/dtmin), ST-segment and LVEDP values. Additionally, heart to body weight ratio as an index of myocardial edematous was also increased significantly. However, changes in these parameters in rats fed with cholesterol-rich diet were not significant.Generally, results indicated that the effects of high OxLDL level on electrocardiogram and hemodynamic parameter after MI was more reliable than effects of high LDL level.

BACKGROUND: It is estimated that one-third of infertility cases are due to male factors. Hyper-cholesterolemia is a social problem in many developed countries and contributed with a heterogeneous group of disorders characterized by an excess of cholesterol and its derivatives in the blood stream. PURPOSE: The objective of the present study was to investigate the protective effects of coenzyme Q10 and L-Carnitine supplementation on semen parameters, sperm function and reproductive hormone profiles in male Wistar rats with high LDL and Oxidized LDL (OxLDL) blood levels. METHODS: Animals were fed with cholesterol and oxidized cholesterol-rich diets for 14 weeks to elevate the LDL and OxLDL blood level, respectively. Pretreatment with coenzyme Q10 (10 mg/kg/day, oral) and L-Carnitine (350 mg/kg/day, oral) were conducted for 5 consecutive weeks. Sex hormones levels, malondialdehyde and total antioxidant concentrations, as well as testis, epididymis and seminal vesicle weight were also analyzed. RESULTS: Following high LDL and OxLDL blood levels, decrease in the sperms count and viability, weights of testis, epididymis and seminal vesicle as well as concentration of testosterone and LH hormone were observed. On the other hand, in contrast to reduction of total antioxidant level, malondialdehyde concentration, both in serum and testis, was increased. However, pretreatment with L-carnitine and coenzyme Q10 increased serum sex hormones level and improved semen parameters significantly. CONCLUSION: Overall, pretreatment with coenzyme Q10 and L-Carnitine attenuated the destructive effects of high LDL and oxidized LDL levels on spermatogenesis parameters in male rats.

We report the case of a 66-year-old Iranian woman with a phaeohyphomycotic cyst (approximately 3×2.5cm in size) on the right lateral side of the neck. She had dysphagia and hoarseness, without any pain. She complained about discharge of black liquid on the skin and irritation. Histological examination of biopsy fragments from the lesions showed septate, branched brown hyphae. The fungus was cultured, but sporulation remained absent from 4- week-old cultures on Sabouraud dextrose agar (SDA), malt extract agar (MEA), potato dextrose agar (PDA), and water agar with sterile filter paper. Identification with the genus Chaetomium was achieved by sequencing the internal transcribed spacer (ITS) and the small subunit (SSU) domains of the rDNA gene and comparison with sequences held at GenBank and at the Centraalbureau voor Schimmelcultures (CBS). Sequencing of the SSU rRNA gene reveals this strain as belonging to the genus Chaetomium. The sequence of ITS did not fully match with any sequence of available ex-type strains of Chaetomium, Thielavia, Madurella and Papulaspora and hence might belong to an undescribed species. However, without diagnostic morphological features the taxon cannot be introduced as a novel member of the genus Chaetomium. After local excision of the cyst and antifungal therapy with ketoconazole (200mg twice a day), the lesion regressed and healed completely.

Nowadays, cardiovascular diseases and male infertility are two big health problems in industrial countries.The aim of the present study was to investigate the protective role of coenzyme Q10 and L-Carnitine pretreatment in the impaired spermatogenesis caused by isoproterenol (ISO) in male rats.Thirty-two male Wistar rats were allocated in 4 groups. ISO was injected for 2 consecutive days (100 mg/kg) in ISO treated groups. Before ISO administration, pretreatment with Coenzyme Q10 (10 mg/kg/day) and L-Carnitine (350 mg/kg/day) were conducted for 20 consecutive days. Sex hormones level, malondialdehyde (MDA) and total antioxidant concentration as well as testis, epididymis and seminal vesicle weight were investigated.Increase in the concentration of MDA and decrease in total antioxidant level was observed following ISO administration. Accordingly, the sperm viability as well as testis, epididymis and seminal vesicle weights were decreased. In the case of sex hormones, the testosterone and LH levels were decreased and the concentration of FSH was increased. Pretreatment with L-carnitine and Coenzyme Q10 significantly decreased the MDA level and increased total antioxidant, LH and testosterone levels. Pretreatment with L-carnitine and Coenzyme Q10 also improved semen parameters and organs weight which were impaired by ISO administration.L-carnitine and Coenzyme Q10 pretreatment could protect spermatogenesis in male rats with ISO administration.

Background: Exposure to house dust mites (HDMs) is a major risk factor for the development of allergic symptoms. HDMs are worldwide in distribution. Assessing these allergens in each area is a critical step in evaluating the risk of sensitisation and controlling allergic symptoms. The aim of the present study was to evaluate the level of major HDMs, Der p 1 and Der f 1, in various parts of Iran. Methods: In 2009, 257 dust samples were obtained from living rooms carpets in seven cities throughout Iran with different geoclimatic conditions. The level of Der p 1 and Der f 1 was measured by commercial ELISA. Results: Detectable level of Der p 1 and Der f 1 levels were only found in Gorgan and Sari, two cities near the Caspian Sea with moderate temperatures and high relative humidity. In both of these cities, Der f 1 was more frequent than Der p 1 (100% vs. 85%) and was found to be at a higher level than Der p 1 (geometric mean 3128 vs. 439 ng/g dust, P < 0.001). Conclusion: The results of this study confirm that house dust mites in Iran are restricted to the Caspian Sea coastal areas, and in other parts, due to seasonal variations of temperature and humidity mites are not able to grow well and therefore are not an important risk factor for sensitisation and respiratory allergies (AU)

Mutations within the coding region of hepatitis B surface antigen (HBsAg) have been found naturally in chronic carriers. To characterize the mutations of HBsAg from Iranian chronic carriers who were vaccine and/or medication naive. The surface genes from 360 patients were amplified and directly sequenced. The distribution of amino acid substitutions was classified according to different immune epitopes of the surface protein. All isolates belonged to genotype D. 222 (61.6%) of 360 patients contained at least one amino acid substitution. 404 (74.5%) of 542 amino acid changes occurred in different immune epitopes of HBsAg, of which 112 (27.7%) in 32 residues of B-cell epitopes (62 in the 'a' determinant); 111 (27.4%) in 32 residues of T helper; and 197 (48.7%) in 32 residues inside cytotoxic T lymphocyte (CTL) epitopes. One Th (186-197) and two CTL (28-51 and 206-215) epitopes were found to be hotspot motifs for the occurrence of 213 (52.7%) substitutions. 20 stop codons were identified in different epitopes. There was a significant association between amino acid substitutions and anti-HBe seropositivity; however, the correlation between such changes with viral load and ALT levels was not significant. In chronic hepatitis B virus(HBV) carriers, positive selection in particular outside the 'a' determinant appeared to exert influence on the surface proteins. These changes could be immune escape mutations naturally occurring due to the host immune surveillance especially at the T-cell level.

Severe hypertension occurred as a postoperative complication after correction of a club-foot deformity in four children (seven feet) who were between the ages of two and three years and had no history of hypertension. The hypertension subsided slowly after administration of antihypertensive medications or more rapidly after release of the correction that had been obtained operatively.
