Abstract
Monogenean trematodes, particularly those belonging to the Diplectanidae family, are significant metazoan parasites with substantial implications for aquaculture expansion. This study, investigatied the occurrence, prevalence, and pathological impact of Diplectanum spp. in European seabass (Dicentrarchus labrax) across three distinct Egyptian fish farms. During 2021-2022, we sampled 1800 European seabass (Dicentrarchus labrax) from three Egyptian fish farms (600 fish per farm). Farms 1 and 2 used semi-intensive earthen pond systems, while Farm 3 utilized an intensive floating cage system. Employing Clinical, post-mortem, parasitological, and molecular examination technique. Pathological lesions were identified, including skin and gill discoloration, emaciation, and internal organ abnormalities. Seasonal prevalence exhibited significant variations between farms, with highest rates observed in spring and Farm 3 reached an overall peak prevalence of 84.67 %. Parasitological examination distinguished two Diplectanum species morphologically, while molecular techniques exhibited limited specificity. Histopathology unveiled damage to gill, liver, spleen, kidney, and intestine, attributed to Diplectanum haptors including inflammation and internal bleeding, potentially leading to secondary infections. Molecular identification via PCR targeting ITS and 28SrDNA genes, revealing similar band sizes for the two Diplectanum species, indicating limited intraspecific genetic diversity. The study emphasizes investigating parasitic infections' prevalence and impact in aquaculture, necessitating robust molecular techniques for species differentiation. This study underscores the importance of investigating the prevalence and impact of parasitic infections in aquaculture. It highlights the need for robust molecular techniques to differentiate species. By focusing on Diplectanum spp. infections in D. labrax, the study offers valuable insights into managing parasites in aquaculture effectively.

Abstract
This study aimed to investigate the relationship between seasonal variations, water parameters and the prevalence of Vibriosis in Gilthead seabream. A total of 160 Gilthead seabream fish were sampled over the course of 1 year from private earthen pond farms in the Suez Canal area and examined for abnormalities and internal lesions. Vibrio alginolyticus, the causative agent of Vibriosis, was isolated and characterized from the sampled Gilthead seabream fish. The study revealed a significant correlation between different seasons and the prevalence of V. alginolyticus, with lower occurrence during autumn. Analysis of water parameters showed that toxic ammonia concentration was not effective in distinguishing between positive and negative cases of V. alginolyticus. Dissolved oxygen showed weak predictive ability for the occurrence of V. alginolyticus, while temperature demonstrated moderate potential as a predictor of its prevalence. pH values, organic matter concentrations and salinity showed no significant association with the occurrence of V. alginolyticus. Experimental challenges highlighted the vulnerability of Gilthead seabream to V. alginolyticus and emphasized the impact of environmental factors, such as pH and toxic ammonia, on their mortality and survival. The study emphasizes the importance of considering seasonal changes and water quality parameters in managing V. alginolyticus in mariculture. It underscores the need for careful monitoring and control of environmental factors to ensure the health and well-being of cultured fish populations. The findings contribute to our understanding of Vibriosis management and provide valuable insights for developing effective strategies in the aquaculture industry.

Abstract
The objective of the present study was to demonstrate the blood flow velocities, blood flow rate (BFR; bpm) with the accurate ratio of both systolic and diastolic velocities points (S/D) in addition to Doppler indices (resistive and pulsatility index [RI and PI]) in both fetal [fetal heart (FH), fetal abdominal aorta (Ab. A), and umbilical artery (UM.A)] and maternal [Middle uterine artery (MU.A)] sides during the last month of gestation. Ten Zaraibi (Egyptian Nubian) goats weighing 40-50kg and aged from 5-7 years were examined twice per month till reached the last month of pregnancy. Then all females were examined every 5 days starting from day -35 till day -1 before kidding.The pregnant goats were examined by ultrasonic and Doppler indices were recorded with Doppler scanning (7.5 -12 MHz, with colored and spectral graph to form the perfect wave to assess Doppler measurements). The obtained data were analyzed using analysis of variance. Results indicated that on the fetal side; the maximum point of velocity (MSV; cm/sec) in the FH and BFRwere elevated from day -35 till day -10 with a slight decline at days -5 and -1 at the peripartum period (P < 0.05), while FH.PI and S/D ratio declined till day -1(P < 0.05). In addition, the fetal Ab. A, and UM.A PI, RI, and S/D ratio declined from day -35 till day -1 at the peripartum period with a significant increase in the peak systolic velocity (PSV) and BFR(P < 0.05). However, non-significant changes in the end diastolic velocity (EDV) were detected. On the maternal side, the MU.A PI and S/D declined from day -35 till day -1 with an elevation of both PSV and BFRat the same time points (P < 0.05). In conclusion, the Doppler evaluation of fetal and maternal blood flow vessels is important to give complete information that directly affects the health status of the mother and fetus.

Abstract
Alzheimer's disease (AD) is marked by reduced acetylcholine receptor (AChR) density and an increase in nucleotide oligomerization domain (NOD)-like receptors NLR family, pyrin domain containing 1 (NLRP1). We examined the effect of swimming and consumption of clove supplements on memory, dark cells, and α7nAChR and NLRP1 mRNA and protein expression in the hippocampus of the rat model of AD. Forty-eight rats were divided into six groups: sham (sh), healthy-control (HC), Alzheimer (-control (AC), -training (AT), -training-supplement (ATS), and -supplement (AS)). Alzheimer was induced by injection of amyloid β1-42 (Aβ1-42). Swimming exercise protocol (30 min) and gavaging clove supplement (0.1 mg/kg) were administered daily for three weeks. The results indicated that in response to AD, α7 nicotinic acetylcholine receptor (α7nAChR) mRNA and protein rate (p = 0.001) and memory (p = 0.003) were significantly decreased. In contrast, NLRP1 mRNA and protein rate (p = 0.001) and dark cells (p = 0.001) were significantly increased. This is while exercise and clove supplementation improved Alzheimer-induced changes in α7nAChR, NLRP1, memory, and dark cells (p < 0/05). The present study indicated that exercising and consuming clove supplementation could improve memory by increasing α7nAChR and decreasing NLRP1 and dark cells.

Abstract
BACKGROUND The testes are highly susceptible to the adverse effects of chemotherapy and radiation at all stages of life. Exposure to these threats mainly occurs during cancer treatment and as an occupational hazard in radiation centers. The present study investigated the regenerative ability of adipose-derived mesenchymal stem cells (ADMSCs) against the adverse effects of cisplatin on the structure and function of the testes. METHODS New Zealand white rabbits (N = 15) were divided into three groups of five: a negative control group (no treatment), a cisplatin group (single dose of cisplatin into each testis followed three days later by a PBS injection), and a cisplatin + ADMSCs group (cisplatin injection followed three days later by an ADMSC injection). On day 45 post-treatment, serum testosterone levels were evaluated, and the testes and epididymis were collected for histology, oxidative stress examination, and epididymal sperm analysis. RESULTS Cisplatin caused damage to the testicular tissue and decreased serum testosterone levels, epididymal sperm counts, and oxidants. An antioxidant imbalance was detected due to increasing malondialdehyde (MDA) and reduced glutathione (GSH) levels in testicular tissue. The ADMSC-treated group displayed a moderate epididymal sperm count, adequate antioxidant protection, suitable hormone levels, and enhanced testicular tissue morphology. CONCLUSIONS ADMSCs treatment repaired damaged testicular tissue, enhanced biochemical parameters, and modified pathological changes caused by cisplatin.

Abstract
AbstractThis study aimed to determine the effects of melatonin administration on testicular vascular perfusion in relation to steroid hormones and semen characteristics in dogs. The study included 12 normospermic German shepherd dogs (weighed 35 ± 0.5 kg and aged 4 ± 0.5 years). Males received a single melatonin administration (melatonin dimethyl sulfoxide + corn oil via subcutaneous route; MEL; n = 6), while the rest of the animals served as controls (dimethyl sulfoxide + corn oil; Control; n = 6). Males were subjected to routine examination on days -15, 0, 15, 30, 45, and 60. All examined dogs were subjected to Doppler screening, semen collection, and blood sampling. The MEL group showed a significant (P < 0.05) elevation in semen volume, concentration, percentage of sperm motility, and total sperm × 106 / ejaculate compared to other control males. Doppler indices as resistance (RI) and pulsatility (PI) indices declined (P < 0.05) from D 30 (1.02 ± 0.01) until day 60 (0.87 ± 0.02) of treatment. In MEL males, the peak systolic point of velocity (PSV; cm/sec) of the testicular artery elevated (P < 0.05) on day 60 (20.15 ± 0.99) compared to its value on day 0 (17.39 ± 1.84). On D 60, the levels of testosterone (T), estradiol 17-ß (E2), and nitric oxide (NO) elevated (P < 0.05). A negative correlation was detected between testicular volume, scrotal circumference (SC), T levels, Doppler indices, and velocities. In conclusion, single melatonin administration could improve testicular vascularization via increasing Doppler velocities and intratesticular colored areas. In addition, it could improve semen picture and steroids (T and E2) and nitric oxide.

Abstract
AIM The aim of this study was to investigate the effect of applying I Pass the Baton (IPB) on the quality of handoff among nurses. METHOD The present study was a quasi-experimental study. All nurses of the internal wards of Sanandaj educational hospitals, Kurdistan Province, Iran were selected by census method and randomly assigned to intervention (n=34) and control (n=31) groups. Handoff quality was measured by self-report and observation methods. The intervention included a face-to-face training session, training on how to use the IPB, inserting the IPB chart into the patient file, training leaflet, and installing a poster in the ward. The Situation, Background, Assessment, Recommendation (SBAR) was used according to routine practice in the control group. Descriptive and inferential tests were applied to analyze the data using SPSS-16. RESULTS The mean score of handoff quality was 82.61±12.77 and 107.11±7.97 before and after the intervention in the intervention group (p<0.05) and 89.00±0.34 and 85.64±19.19 before and after the intervention in the control group, respectively (p=0.91). There was a statistically significant difference between the two groups after the intervention (p<0.05). Implementation of the training program and the IPB tool improved the handoff quality in terms of interaction and support, patient involvement, information quality, and efficiency. CONCLUSIONS The IPB has various indicators of patient participation and includes the criteria needed for patient evaluation. Therefore, it can be used to handoff a wide range of patients in the internal ward.

Abstract
Oxidative stress (OS) is brought on by heat stress (HS), which weakens antioxidant defense and initiates OS. Since mitochondria are the primary source of reactive oxygen species (ROS), HS-mediated OS may be lessened by targeting mitochondria with particular antioxidants. The purpose of this study was to investigate the effect of oral coenzyme Q10 (CoQ10) supplementation on the reproductive performance of goat bucks under HS conditions. Ten mature bucks were randomly separated into two groups and housed in an environment with a high-temperature humidity index (THI: 88.3 to 94.8; summer season). The first group (n = 5) got the baseline diet while the second group (n = 5) received supplemental oral CoQ10 (3 mg/kg BW; CoQ10 group) daily for six weeks. Testicular blood flow parameters (TBF), testicular volume (TV) and echogenicity (TE), nitric oxide (NO), seminal alanine aminotransferase (ALT) and catalase (CAT) activities, total antioxidant capacity (TAC), malondialdehyde (MDA) content, and semen quality traits were all measured. The examinations started a week before (W-1), on the first supplementation day (W0), and weekly for eight consecutive weeks (W1-W8). There were marked (P < 0.05) increases in TBF (W3-W6) and TV, and a decrease in TE (W3-W5) in the CoQ10 group compared to the CON group. Similarly, testosterone (T) and NO levels (W3-W5) in the CoQ10 group were higher (P < 0.05) than those of the control group. The CoQ10 group demonstrated significant (P < 0.05) increases in seminal CAT (W4-W8) and TAC (W2-W6) activities and decreases in ALT (W4-W7) activity and MDA (W5-W8) concentration as compared to the control group. The CoQ10 group showed improvements (P < 0.05) at W3-W6 for sperm progressive motility, viability, and normal morphology and at W6-W8 for sperm concentration. In conclusion, oral CoQ10 supplementation improved testicular hemodynamics, testosterone production, semen quality, and antioxidant capacity in goat bucks during summer heat stress conditions.

Abstract
Contrary to several vaccination programs to protect against bird flu and Newcastle disease (ND), these diseases remain a significant threat to the poultry industry. Improving the immune responses is important for many reasons such as vaccine failure, immunosuppressive diseases, and antibiotics misuse. Nowadays, research on materials likely to have immune-enhancing effects is increasing. Factors, substances, or compounds that can regulate different functions of the immune system can be used to enhance specific and even nonspecific responses to vaccines. The ability of herbal extracts to improve the immune system supports their use as immune stimulants. The present study aimed to examine the effects of barley malt extract in drinking water on humoral immunity of broiler chickens against ND and Avian Influenza (AI) disease subtype H9N2 vaccines. A total of 225 one-day-old broiler chicks (Ross strain) were divided into 5 groups of 3 subgroups and each subgroup had 15 chicks. Group A, B, and C chickens received 0.2%, 0.3%, and 0.5% of malt extract respectively in drinking water. Group D chickens did not get malt extract. Group E chickens did not receive malt extract and Newcastle and AI vaccines as the control group. All groups except group E were vaccinated with live Newcastle vaccine (B1 strain) intraocularly and AI-ND subtype H9N2 killed vaccine subcutaneously on the 7th day. Antibody titer against NDs and AI vaccines was considered by the Hemagglutination Inhibition test (HI test). Malt extract at 0.5% concentration, at all periods after vaccination, enhanced the systemic antibody response to ND vaccine in broiler chickens, but this extract had no significant effect on antibody response against the AI vaccine.Conclusion: Inoculation of ND vaccines with barley malt extract as an immune-boosting agent induces extensive immune responses involved in HI-NDV Ab titers.

Abstract
Fifteen cyclic, multiparous goats were equally stratified and received the common Ovsynch protocol (GPG: intramuscular, IM, injection of 50 mg gonadorelin, followed by an IM injection of 125 µg cloprostenol 7 days later, and a further IM injection of 50 mg gonadorelin 2 days later) or the Ovsynch protocol using nanofabricated hormones with the same dosages (NGPG) or half dosages (HNGPG) of each hormone. The ovarian structures and ovarian and luteal artery hemodynamic indices after each injection of the Ovsynch protocol using B-mode, color, and spectral Doppler scanning were monitored. Levels of blood serum progesterone (P4), estradiol (E2), and nitric oxide (NO) were determined. After the first gonadotrophin-releasing hormone (GnRH) injection, the number of large follicles decreased (p = 0.02) in NGPG and HNGPG, compared with GPG. HNGPG resulted in larger corpus luteum (CL) diameters (p = 0.001), and improved ovarian and luteal blood flow, compared with GPG and NGPG. Both NGPG and HNGPG significantly increased E2 and NO levels compared with GPG. HNGPG increased (p < 0.001) P4 levels compared with GPG, whereas NGPG resulted in an intermediate value. After prostaglandin F2α (PGF2α) injection, HNGPG had the largest diameter of CLs (p = 0.001) and significantly improved ovarian blood flow compared with GPG and NGPG. Both NGPG and HNGPG increased (p = 0.007) NO levels, compared with GPG. E2 level was increased (p = 0.028) in HNGPG, compared with GPG, whereas NGPG resulted in an intermediate value. During the follicular phase, HNGPG increased (p = 0.043) the number of medium follicles, shortened (p = 0.04) the interval to ovulation, and increased (p < 0.001) ovarian artery blood flow and levels (p < 0.001) of blood serum P4, E2, and NO, compared with GPG and NGPG. During the luteal phase, the numbers of CLs were similar among different experimental groups, whereas the diameter of CLs, luteal blood flow, and levels of blood serum P4 and NO increased (p < 0.001) in HNGPG, compared with GPG and NGPG. Conclusively, the nanodelivery system for the Ovsynch protocol could be recommended as a new strategy for improving estrous synchronization outcomes of goats while enabling lower hormone dose administration.

Abstract
We compared the prognosis of inpatients with a known diagnosis of Alzheimer's or Parkinson's disease who have COVID-19 infection with other hospitalized patients with COVID-19. Our cohort study started in October 2020 and ended in May 2021 and included inpatients with COVID-19 infection who were admitted to hospitals. From a total of 67,871 patients with a confirmed diagnosis of COVID-19, a sample of 3732 individuals were selected of which 363 had Alzheimer's, and 259 had Parkinson's disease. All patients had both positive RT-PCR test and positive chest CT for COVID-19. The outcome was dead within 28 days of admission and the predictors were a large number of demographic and clinical features, and comorbidities recorded at patients’ bedside. Mortality were 37.5%, 35.1%, and 29.5% in patients with Alzheimer's disease, Parkinson's disease; and in other patients, respectively. The hazard ratio for Alzheimer's disease was 1.27 (95% CI, 1.06–1.53, p = 0.010) and for Parkinson's disease was 1.17 (95% CI, 0.94–1.46, p = 0.171). Age was a predictor of mortality, hazard ratio = 1.04 (95% CI, 1.03–1.05, p < 0.001). Patients with Alzheimer's disease and COVID-19 infection were older and more likely to have a loss of consciousness on admission (both p ≤ 0.001). We concluded that inpatients with Alzheimer's disease have an increased risk for 28-day mortality from COVID-19 and healthcare settings should be ready to provide critical care for them such as early intubation and immediate O2 therapy. However, Parkinson's disease does not significantly predict higher mortality of COVID-19.

Abstract
The objective of this study was to investigate the effect of Spirulina platensis extract (SPE) addition to the freezing extender on freezability, lipid peroxidation, ultrastructure alterations and fertilizing potentials of frozen-thawed buffalo bull spermatozoa. Semen samples were collected with artificial vagina from five adult fertile bulls and diluted with Tris-base extender containing SPE (1, 5, 10 and 20 μg/mL) or without SPE (control). Diluted semen was cooled to 4 °C throughout one hour and frozen in 0.25 mL straws: prior to being stored in liquid nitrogen. Cryopresreved spermatozoa were assessed for post-thawing sperm motility, viability, acrosomal integrity, ultrastructure changes, antioxidant activities, lipid peroxidation and fertility rate. The current results clearly indicated that adding 10μg/mL SPE to the freezing extender significantly improved (P< 0.05) post-thawing motility and decrease the percentage of acrosomal damage (51.67±6.02% and 16.33±1.46%, respectively) compared with the control (28.33±4.41% and 26.33±1.77%, respectively). Moreover, addition of 10 μg/mL SPE to the semen extender significantly diminished (P< 0.05) MDA concentration (10.66±2.40 nmol/109) compared with the control (22.66±4.26 nmol/109). Therefore, the present results revealed that addition of 10μgl/mL SPE to the freezing extender might improve semen quality and reduce cryodamage of the buffalo bull spermatozoa.

Abstract
The positive impact of melatonin on in vitro embryo production (IVEP) has been reported in many domestic species; however, no studies have been carried out in camelids. We aimed to evaluate the effects of melatonin supplementation in maturation media on in vitro maturation, fertilization, and preimplantation embryo development of dromedary camel oocytes (experiment 1). We also evaluated the concentrations of total antioxidant capacity (TAC), and malondialdehyde (MDA) in the IVM spent medium in relation to melatonin supplementation. Cumulus oocyte complexes (COCs) were cultured in in vitro maturation media (IVM) supplemented with either 0.0, 25.0, 50.0 or 75.0 μM of melatonin for 30 h. Matured oocytes were then fertilized in vitro with epididymal camel spermatozoa. Following IVF, the resulting embryos were cultured in vitro for seven days. The percentage of maturation, fertilization, cleavage, and embryo developmental rates (morula and blastocyst) was recorded (experiment 1). TAC and MDA levels in the IVM spent maturation media were also evaluated at 30 h post-IVM (experiment 2). The results showed that supplementation of IVM media with 25 μM melatonin significantly improved oocyte nuclear maturation, fertilization (18 h post-insemination; pi), cleavage (day 3 pi), morula (day 5 pi) and blastocyst (day 7 pi) rates as compared with the controls and other melatonin-supplemented groups. Furthermore, the TAC in the IVM spent media was significantly increased (P < 0.05) in 25 μM melatonin supplemented groups than those supplemented with 0.0, 50.0, 75.0 μM melatonin. However, the concentration of MDA was significantly lower (P < 0.05) in IVM media supplemented with 25.0 μM of melatonin when compared with the control and other treatment groups. In conclusion, supplementation of IVM medium with 25 μM of melatonin could enhance the in vitro developmental capacity of dromedary camel oocytes.

Abstract
Aim: Several factors had been concerned with the developmental competence of the sheep oocyte. This study aims to investigate the effect of adding growth factors (insulin-like growth factor 1 [IGF-1] and epidermal growth factor [EGF]) in the maturation medium of ewe oocytes selected based on brilliant cresyl blue (BCB) screening on in vitro maturation (IVM), fertilization, and pre-implantation embryo development. Materials and Methods: Cumulus-oocyte complexes (COCs) were obtained from the ovaries of slaughtered ewes by either aspiration or slicing techniques. COCs were in vitro matured in a medium containing IGF-1 and EGF (control group). For BCB screening, oocytes were stained and divided into BCB+ oocytes that matured in the same maturation conditions without adding growth factors (Group 2) or in the presence of growth factors (Group 3), and BCB− oocytes that matured in medium without growth factors (Group 4) or with growth factors (Group 5). Results: The supplementation of the maturation medium with growth factors during IVM of (BCB+) oocytes resulted in a significant increase in nuclear maturation rate (90.9%), fertilization rate (75.6%), and embryo developmental rates (60.0%, 46.7%, and 33.3% for cleavage, morula, and blastocyst, respectively). Conclusion: Culturing BCB+ oocytes in a maturation medium containing both EGF and IGF-1 showed a significant improvement in nuclear maturation, fertilization, and pre-implantation embryo development in vitro.

Abstract
The use of combined systemic retinoids and intralesional immunotherapy in the management of warts is still debatable without straightforward evidence. Through network meta-analysis, the current study evaluated the efficacy and safety of systemic retinoids alone or combined with other remedies in the treatment of warts. We searched six literature databases for clinical trials that compared systemic retinoids to local treatments or placebo in wart management. Outcomes were calculated as odds ratios (OR) with 95% confidence-interval. We used the R software to perform conventional and network meta-analyses (with a frequentist approach). Network meta-analysis of eight trials showed that oral acitretin plus intralesional Candida Ag (OR = 367.71), INF-α plus oral isotretinoin (OR = 223.77), oral acitretin (OR = 117), Candida Ag (OR = 91.93), oral isotretinoin (OR = 62.26) and topical isotretinoin (OR = 17.69) had higher complete recovery rates than placebo. Regarding the P-score, oral acitretin plus intralesional Candida Ag had the highest efficacy in achieving complete response (P-score = 0.88), followed by INF-α plus oral isotretinoin (P-score = 0.79), then oral acitretin (P-score = 0.60). Variable baseline characteristics and lack of data on some outcomes. The current study shows the efficacy for systemic retinoids in the treatment of warts, especially reluctant or recurrent types. Moreover, combinations of systemic retinoids with intralesional immunotherapy yield higher rates of complete clearance with lower recurrence.

Abstract
BACKGROUND Prevalence of hepatitis B virus (HBV) infection has been reported to be higher in the institutionalized mentally disabled patients than that of the general population previously reported in Iran. This study aims to investigate HBV infection among nurses and families of the hospitalized mentally disabled patients. MATERIAL AND METHODS This study was conducted on 110 nurses and family members of the mentally disabled patients who were hospitalized in five residential care centers of Tehran. The presence of hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (HBcAb) was examined using the enzyme-linked immunosorbent assay (ELISA). Afterwards, HBV DNA was extracted, and then propagated via a nested polymerase chain reaction (PCR) and specific primers. Finally, a phylogenetic tree was constructed using the neighbor-joining method to compare virus genomes in the nurses' serum with other isolated HBVs worldwide. RESULTS Out of 102 studied nurses, three (3%) were positive for HBsAg (100% female). Also, no patient was positive for the HBV genome, while eight (7.3%) nurses were positive for HBcAb including two (25%) males and six (75%) females. Genome sequencing of one DNA positive sample showed that the isolated virus from this patient contained sub genotype D1 and subtype ayw2. The results of none of the family members were positive for HBsAg, HBcAb, or HBV DNA. CONCLUSION This study showed a higher prevalence of HBsAg among nurses (3%) compared to the Iranian general population (1.7-2.1%). The virus isolated from the nurses belonged to subgenotype D1 and subtype ayw2 in accordance with previous Iranian reports. Also, there was no drug-resistant or vaccine-escape mutations in the obtained viral genome. Moreover, low immune pressure on the virus in the asymptomatic chronic HBV patients might be responsible for low nucleotide divergence among the derived HBV genome.

Abstract
BACKGROUND AND OBJECTIVE To use siRNA molecule as a therapeutic agent in gene silencing, an efficient delivery system is necessary. Stability and clearance by reticuloendothelial of siRNA still remains the major challenges for clinical application. Herein, we could develop new lipid-polymer hybrid nanoparticles (LPHNP) as a siRNA carrier to silence insulin-like growth factor type I (IGF-1R) gene overexpression in MCF-7 human breast cancer cell line. METHODS Dimethyldioctadecylammonium bromide-methoxy poly(ethylene glycol)-poly (ε-caprolactone) (DDAB-mPEG-PCL) LPHNPs were synthesized using a single step nanoprecipitation method and characterized by dynamic light scattering (DLS) and atomic force microscopy (AFM) microscope. Cytotoxicity of the nanoparticles was assessed in the MCF7 cell line using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Desired LPHNP-siRNA complex was determined using different Nitrogen:Phosphate ratio (N/P) ratios and gel retardation. To determine the encapsulation efficiency of siRNA (%) in LPHNP, its absorbance was measured. The effect of the siRNA-LPHNP complex on IGF-1R silencing was assessed by reverse transcription-polymerase chain reaction (RT-PCR) RESULTS: LPHNP was synthesized using a single-step sonication method with a size below 100 nM. The viability of cells treated with hybrid nanoparticles was significantly greater than the corresponding cationic lipid (P < 0.01). As demonstrated by gel retardation assay, efficient siRNA binding to LPHNP occurred at N/P equal to 40 and siRNA encapsulation efficiency was found to be 95% ± 4 at this ratio. LPHNP-IGF-1R siRNA complex could be able to down-regulate the target more efficiently when it compared with the corresponded controls (P < 0.001). CONCLUSION In conclusion, our results suggest that DDAB cationic lipid and mPEG-PCL copolymer hybrid nanoparticle may be a good candidate for efficient siRNA delivery.

Abstract
The objectives of the current study were to compare the use of a single bilateral intratesticular injection of 2 different volumes of glycerol 70% (0.5 and 1.0 mL) as a method of chemical sterilization and the application of 2 surgical procedures (orchiectomy and vasoligation). Animals were classified into 4 groups. Group 1:10 cats were subjected to a conventional bilateral orchidectomy. Group 2:6 cats were subjected to a bilateral vasoligation of the testicular blood supply without removing the testicles. Group 3:7 cats were subjected to a single intratesticular injection of 0.5 mL glycerol bilaterally and Group 4:7 cats were subjected to a single intratesticular injection of 1.0 mL glycerol bilaterally. Serum testosterone concentration (ng/mL) and average testicular length (cm) were measured just before (control) and weekly after orchiectomy (only serum testosterone concentration), vasoligation, and intratesticular treatment for 3 consecutive weeks. After 2 months from testicular vasoligation (group 2) and intratesticular administration (group 3 and 4), castration was performed for all cats. The epididymal sperm count and the histopathological findings were recorded for all groups after the orchidectomy. In group 2 serum testosterone level was significantly (P ˂ .01) decreased from (4.14 ± 1.10 ng/mL) before vasoligation (control) to (1.71 ± 0.34 ng/mL) 3 weeks postoperation. In group 4 a significant (P ˂ .01) decrease in serum testosterone concentration was recorded 2 and 3 weeks postinjection (1.41 ± 0.31 and 1.32 ± 0.21 ng/mL, respectively). There was a significant decrease in the testicular length 1 week after the vasoligation (group 2) and the testicular treatment (group 4) compared with preoperative controls of the 2 groups. Besides, the epididymal samples collected from groups (2 and 4) showed azoospermia. In conclusion, a bilateral intratesticular injection of 1.0 mL glycerol (70%) as a chemical method of tomcat sterilization can replace the surgical orchidectomy besides being less invasive and less traumatic and gave better results than using the intratesticular injection of 0.5 mL glycerol.

Abstract
Autoimmune blistering diseases can eventually cause life-threatening complications if left untreated. Although there is no cure for these bullous diseases; their therapy is based on suppressing the immune system to cease the de novo formation of the generated antibodies. The current study aimed to assess the safety and efficacy of using standing alone alternative therapies beyond systemic steroids for management of autoimmune bullous diseases. We searched six literature databases for both randomized and quasi-randomized clinical trials that assessed the efficacy of drugs other than systemic steroids in autoimmune bullous diseases. Outcomes were calculated as odds ratios with 95% confidence-interval. We used the R software to perform conventional and network meta-analyses with a frequentist approach. The network ranking order for 629 bullous pemphigoid patients, from the best to the worst was, clobetasol propionate cream (40 mg; (P-score = .87), clobetasol propionate cream (10-30 mg; P-score = .77), nicotinamide plus tetracycline (P-score = .56), steroids (P-score = .29) and doxycycline (P-score = .01). Limitations of this study are the small sample of the included studies except for blister trial and lack of randomization in most trials. To conclude, Combined doxycycline and nicotinamides are safer and more effective option for extensive bullous pemphigoid patients than the usual use of systemic steroids. For limited disease, topical corticosteroid (40 mg/d) use provides a safer and better response modality than the other proposed treatments.

Abstract
Background:Autoantibodies that target aminoacyl transfer(t) RNA synthetases (aaRS) represent the serological marker of the anti-synthetase syndrome (ASS), a major subgroup of the idiopathic inflammatory myopathies (IIM) (1). Among the anti-aaRS, anti-histidyl tRNA synthetase (HisRS) autoantibodies (anti-Jo1) are the most common. Up to 90% of IIM/ASS patients diagnosed with interstitial lung disease (ILD) harbor anti-Jo1 autoantibodies (2).Objectives:Reactivity and affinity of anti-Jo1 autoantibodies from serum and broncheoalveolar lavage fluid (BALF) were investigated against HisRS autoantigen. Associations with clinical data from patients IIM/ASS were addressed.Methods:Total IgGs were purified by affinity chromatography. Samples and clinical data were obtained from: i) 26 anti-Jo1+patients (19 at diagnosis, 16/19 at follow-up, 7 BALF/matching serum at baseline; ii) 29 anti-Jo1-(25 serum at diagnosis, 4 BALF/matching serum at baseline); iii) 24 age/gender matched healthy controls. Anti-Jo1 IgG and IgA response against HisRS was evaluated by ELISA and western blot. Affinity was measured by surface plasmon resonance. HisRS full-length (HisRS-FL), two HisRS domains (ABD and CD), and two HisRS splice variants (WHEP and WHEP + ABD splice variant (SV)) were tested. Correlations between autoantibody reactivity and clinical data, at baseline and over disease course, were evaluated.Results:Anti-Jo1 autoantibodies from serum and lung bound HisRS-FL, WHEP and SV with high reactivity and affinity already at diagnosis and recognized both conformational and linear HisRS epitopes (Fig. 1). Levels of autoantibodies (against HisRS-FL, -domains and -splice variants) varied among patients and overtime. Patients with ILD, arthritis and less skin involvement presented higher anti-Jo1 titers compared to those with lower anti-Jo1 titers and to the anti-Jo1 negative group (Fig. 2). Anti-WHEP reactivity in BALF strongly correlated with poor pulmonary function.Conclusion:High reactivity and affinity at time of diagnosis indicates that autoimmunity against HisRS is most likely initiated before IIM/ASS diagnosis. Reactivity to specific splice variants of HisRS may be employed as diagnostic and prognostic markers.References:[1]Marguerie C, Bunn CC, Beynon HL, Bernstein RM, Hughes JM, So AK, Walport MJ: Polymyositis, pulmonary fibrosis and autoantibodies to aminoacyl-tRNA synthetase enzymes.

Abstract
Background:Knee osteoarthritis (OA) as a common progressive degenerative condition is one of the most important leading causes of disability and relative dependence. Worldwide prevalence of symptomatic knee OA has estimated 3.8%. It affects more than 20% of over 45-year-old population. Among the minimally invasive methods recommended for knee OA management is intra-articular injections for which a large array of products have been used. Despite all the existing options, there is still no general consensus on the choice and priority of the best intra-articular injection in knee osteoarthritis.Objectives:Our study compare the short and long-term efficacy of the intra articular injections (IAIs) of hyaluronic acid (HA), platelet-rich plasma (PRP), plasma rich in growth factors (PRGF), and ozone in patients with knee osteoarthritis (OA).Methods:In this single-blinded randomized clinical trial, 238 patients with mild to moderate knee OA were randomized into4 groups of IAIs: HA (3 doses weekly), PRP (2 doses with 3 weeks interval), PRGF (2 doses with 3 weeks interval), and Ozone (3 doses weekly). Our outcome measures were the mean changes from baseline until 2,6, and 12 months post intervention in scores of visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne index.Results:A total of 200 patients enrolled final analysis. The mean age of patients was 56.9 ± 6.3 years, and69.5% were women. In 2 months follow up, significant improvement of pain, stiffness, and function were seen in all groups compared to the baseline, but the ozone group had the best results(P<0.05). In 6 month follow up HA, PRP, and PRGF groups demonstrated better therapeutic effects in all scores in comparison with ozone (P<0.05).At the end of the 12th month, only PRGF and PRP groups had better results versus HA and ozone groups in all scores (P<0.05).Despite the fact that ozone showed better early results, its effects begin to wear off earlier than other products and ultimately disappear in 12 months.Conclusion:Ozone injection had rapid effects and better short-term results after 2 months, but its therapeutic effects did not persist after 6 months and at the 6-month follow up, PRP,PRGF and HA were superior to ozone. Only patients in PRP and PRGF groups improved symptoms persisted for 12 months. Therefore, these products could be the preferable choices for long-term management.References:[1]Wang-Saegusa A, Cugat R, Ares O, Seijas R, Cuscó X, Garcia-Balletbó M.

Abstract
Our objective was to assess and rank different pharmacological interventions for relieving endometriosis-related pain. We conducted an online bibliographic search in different databases from their inception until March 2019. We included randomized controlled trials (RCTs) that assessed different medical therapies in the management of endometriosis-related pain. We applied this network meta-analysis (NMA) based on the frequentist approach using statistical package "netmeta" (version 1.0-1) in R software. Our main outcomes were the change in severity of pelvic pain, dysmenorrhea score, non-menstrual pelvic pain score, and dyspareunia score. Overall, 36 RCTs were included in this study (patients no. = 7942). Dienogest (0.94), combined hormonal contraceptives (CHCs) (0.782), and elagolix (0.38) were the highest-ranked interventions for reducing the severity of pelvic pain at three months, while at six months, gonadotropin-releasing hormone (GnRH) analogues (0.75), levonorgestrel-releasing intrauterine system (LNG-IUS) (0.73), and dienogest (0.65) were linked to more reduction in pelvic pain. The ranking p-score showed that GnRH analogues was the highest-ranked treatment for reducing dysmenorrhea at 3 months (1.00), while CHCs were the highest-ranked treatment at 6 months (0.97), followed by GnRH analogues (0.89). GnRH analogues (0.63) and elagolix (0.54) at three months while desogestrel (0.94) and CHCs (0.91) at six months were the highest-ranked treatment to reduce non-menstrual pelvic pain. GnRH analogues and elagolix were the highest-ranked pharmacologic therapies for reducing dyspareunia. In conclusion, CHCs, GnRH analogues, progesterone, and elagolix were the best approaches in reducing the pain of endometriosis.

Abstract
BACKGROUND Cerebral palsy (CP) is a brain disorder that affects the development, movement and posture leading to limitation of Range of Movement (ROM) in the growing children. CP leads to deformities such as equinus foot deformity. We aim to investigate the efficacy of different botulinum toxin (BTX) products with or without serial casting in reducing the muscle spasticity in equinus foot deformity in patients with CP. METHODS A systematic review of the literature was performed by searching different electronic databases. Pub- Med, Scopus, Web of Science (WOS), and GHL databases were used. We analyzed the extracted data by network meta-analysis method using the R software package (version 3.5.0). RESULTS Regarding Modified Ashworth score (MAS), BTX-A was superior compared to placebo and BTX-A plus immediate casting (MD = -0.39, 95% CI [-0.60; -0.18]) and (MD = -0.50, 95% CI [-0.98; -0.02]), respectively. Concerning growth motor function movement Classification System (GMFM), Neuronox ranked above at 3 months (MD = -1.60, 95% CI [-2.87; -0.33]) and at six months (MD = -1.90, 95% CI [-3.48; -0.32]) compared to BTX-A. Regarding the Modified Tardieu scale (MTS) with knee flexion, BTX-A was superior to BTX-A plus immediate casting (MD = 8.60, 95% CI [1.76; 15.44]). Concerning passive range of movement (PROM) with Knee flexion or extension at 3 months, BTX-A showed a significant improvement compared to BTX-A plus immediate casting. CONCLUSION BTX-A ranked best on a physician rating scale (PRS), MAS, MTS with knee flexion and PROM (Knee flexion and extension) compared to Neuronox and Botulax. BTX-A alone was also better than BTX-A plus immediate casting.

Abstract
Macroscopic and microscopic findings of Rahmani sheep cervical canal were evaluated for designing a trans-cervical catheter. The study was carried out on 160 cervices divided into four groups: (Group A; young follicular, Group B; old follicular, Group C; young luteal and Group D; old luteal). All morphometric parameters of cervical canals of each group including length, average length and the external os diameter and shape were measured and tabulated. Epoxy casts were made to demonstrate the anatomic variations of each group. Data collected were statistically analysed using ANOVA. One hundred and twenty tissue sections from each group were sectioned and stained with Harris haematoxylin and eosin, Masson’s trichrome stain for demonstration of collagen fibres, Alcian blue pH 2.5 for demonstration of acidic mucins and PAS technique for demonstration of neutral mucins. In conclusion, the current study is the first report on the morphometric structure of the cervical canal of native Egyptian Rahmani ewes.

Abstract
Cryopreservation of oocytes would serve as an alternative to overcome the limited availability of dromedary camel oocytes and facilitate improvements in IVP techniques in this species. Our goal was to develop a protocol for the vitrification of camel oocytes at the germinal vesicle (GV) stage using different cryoprotectant combinations: 20% EG and 20% DMSO (VS1), 25% EG plus 25% DMSO (VS2) or 25% EG and 25% glycerol (VS3) and various cryo-carriers; straws or open pulled-straw (OPS) or solid surface vitrification (SSV); and Cryotop. Viable oocytes were cultured in vitro for 30 h. Matured oocytes were fertilized with epididymal spermatozoa and then cultured in vitro in modified KSOMaa medium for 7 days. Survival and nuclear maturation rates were significantly lower (P ≤ 0.05) in oocytes exposed to VS3 (44.8% and 34.0%, respectively) than those exposed to VS1 (68.2% and 48.0%, respectively) and VS2 (79.3% and 56.9%, respectively). Although recovery rates were significantly lower (P ≤ 0.05) in SSV and Cryotop vitrified oocytes (66.9% to 71.1%) than those vitrified by straws with VS1 or VS2 solutions (86.3% to 91.0%), survival rates were higher in the SSV and Cryotop groups (90.7% to 94.8%) than in the straw and OPS groups (68.2% to 86.5%). Among vitrified groups, maturation and fertilization rates were the highest in the Cryotop-VS2 group (51.8% and 39.2%, respectively). These values were comparable to those seen in the controls (59.2% and 44.6%, respectively). Cleavage (22.5% to 27.9%), morula (13.2% to 14.5%), and blastocyst (6.4% to 8.5%) rates were significantly higher (P ≤ 0.05) in SSV and Cryotop groups than in straws. No significant differences were observed in these parameters between the Cryotop and control groups. We report for the first time that dromedary oocytes vitrified at the GV-stage have the ability to be matured, fertilized and subsequently develop in vitro to produce blastocysts at frequencies comparable to those obtained using fresh oocytes.

Abstract
Cryopreservation of oocyte would be an alternative to overcome the limited availability of dromedary camel oocytes and allow improvements in in vitro production in this species. Our aim was to develop a protocol for vitrification of dromedary camel oocytes at the germinal vesicle (GV) stage using various cryoprotectant combinations and cryo-carriers. In experiment 1, cumulus–ppcyte complexes (COC) obtained at slaughter were equilibrated in a solution composed of 10% ethylene glycol (EG) and 0.25 M trehalose. The oocytes were then exposed for 60 s to vitrification solutions (VS) composed of 20% EG and 20% dimethyl sulfoxide (DMSO; VS1) or 25% EG plus 25% DMSO (VS2) or 25% EG and 25% glycerol (VS3). The COC were then transferred into decreasing concentration of trehalose solution (toxicity test). In experiment 2, COC were randomly divided into 4 groups and vitrified by using straw or open pulled-straw (OPS) or solid surface vitrification (SSV) or cryotop in VS1 or VS2. Following vitrification and warming viable oocytes were matured in vitro for 30 h at 39°C in 5% CO2 in air. Matured oocytes were fertilized in vitro by epididymal spermatozoa of mature male camels and then cultured in modified KSOMaa medium for 7 days. Oocyte viability, maturation, fertilization, and embryo development were evaluated. Data were analysed using one-way ANOVA and t-test. Viability and nuclear maturation rates were significantly lower (P ≤ 0.05) in oocytes exposed to VS3 (44.8% and 34.0%) than those exposed to VS1 (68.2% and 48.0%) and VS2 (79.3% and 56.9%). Although recovery rates were significantly lower (P ≤ 0.05) in oocytes vitrified using SSV or cryotop in either VS1 or VS2 solutions (66.9% to 71.1%) than those vitrified by straws using VS1 or VS2 solutions (86.3% to 91.0%), survival rates were higher in SSV and cryotop groups (90.7% to 94.8%) than straw and OPS (68.2% to 86.5%) groups. Among vitrified groups, maturation and fertilization rates (51.8% and 39.2%, respectively) were the highest in the cryotop-VS2 group. Those values were comparable to those seen in the controls (59.2% and 44.6%, respectively). Cleavage (22.5% to 27.9%), morula (13.2% to 14.5%), and blastocyst (6.4% to 8.5%) rates were significantly higher (P ≤ 0.05) in SSV and cryotop groups than in straws. No significant differences were observed in these parameters between cryotop and control groups. Together, the results show that both vitrification solution and cryodevice affect viability and developmental competence of vitrified/warmed dromedary camel oocytes. We report for the first time that dromedary camel oocytes vitrified at the GV stage have the ability to be matured, fertilized, and subsequently develop in vitro to produce blastocyst embryos at frequencies comparable to those obtained using fresh oocytes.

Abstract
In vitro embryo production (IVP) in the domestic bitch is important for conservation of endangered canids. Compared with various domestic animals, the development of assisted reproductive technologies (ART) in the dog has lagged behind, mainly due to the low percentage of oocytes that can reach metaphase II (MII) stage after in vitro maturation (IVM). Beneficial effects of l-carnitine (LC) on embryonic development in culture have been reported in many mammalian species; however, no studies have been conducted in dogs. The aim of the present study was to investigate the effect of LC supplementation during IVM of canine oocytes on nuclear maturation, fertilization status, and pre-implantation development following IVM/IVF. Cumulus-oocyte complexes (COC) were collected by slicing ovaries obtained from dogs (n = 20, 1 to 6 years of age) after ovariohysterectomy. The COC were subjected to IVM for 72 h in a medium (TCM-199) supplemented with LC at different concentrations (0.1, 0.3, 0.6, 1.0, or 2.0 mg mL−1) or without LC supplements (0 mg mL−1; control). Matured oocytes were fertilized in vitro with frozen–thawed spermatozoa, and presumptive zygotes were cultured in SOF medium for 7 days. Frequencies of nuclear maturation (72 h post-IVM), fertilization rates (18 h post-insemination), and embryo development (Days 2 to 5 post-insemination) were evaluated. Data were analysed by one-way ANOVA followed by Tukey’s multiple comparisons test. Supplementation of IVM medium with 0.3 or 0.6 mg mL−1 LC significantly improved (P ≤ 0.05) maturation (35.4% and 41.4%) and fertilization (21.3% and 25.8%) rates compared with the controls and with other LC-supplemented groups; values ranged from 20.1% to 25.0% for maturation and from 12.1% to 14.6% for fertilization. Cleavage (2- to 16-cell stages) was significantly higher (P ≤ 0.05) in the 0.6 mg mL−1 LC supplemented group than the 0.3 mg mL−1 supplemented group (16.3% v. 13.3%). These values were significantly higher (P ≤ 0.05) than those in other groups. Interestingly, 4.5% of IVM/IVF oocytes were developed to morula in 0.6 mg mL−1 LC supplemented group which was significantly higher (P ≤ 0.05) than those developed in the 0.3 mg mL−1 supplemented group (1.0%). No embryos developed beyond the 2- to 16-cell stage in the rest of the groups. In conclusion, l-carnitine supplementation during IVM is particularly efficient in improving nuclear maturation and pre-implantation embryo development of canine oocytes after IVF. These outcomes are important for the improvement of IVM conditions that can advance the efficiency of ART in dogs.

Abstract
In recent years, with increased the prevalence of viral infections and having no specific for their treatment and also the continuous appearance of resistant viral strains, the finding of novel antiviral agents is necessary. In this study, monoterpenes of thymol, carvacrol, p-cymene and essential oils from Sinapis arvensis L., Lallemantia royleana Benth. and Pulicaria vulgaris Gaertn. were screened for their inhibitory effect against herpes simplex virus type 1 (HSV-1) in vitro on Vero cell line CCL-81-ATCC using a plaque reduction assay. The antiviral activity of three monoterpenes (thymol, carvacrol and p-cymene) and three essential oils were evaluated by cytotoxicity assay, direct plaque test. In addition, the modes of antiviral action of these compounds were investigated during the viral infection cycle. Results showed that the inhibitory concentrations (IC50) were determined at 0.002%, 0.037%, >0.1%, 0.035%, 0.018% and 0.001% for thymol, carvacrol, p-cymene, S. arvensis oil, L. royleana oil and P. vulgaris oil, respectively. A manifestly dose-dependent virucidal activity against HSV-1 could be exhibited for compounds tested. In order to determine the mode of the inhibitory effect, compounds were added at different stages during the viral infection cycle. At maximum noncytotoxic concentrations of the compounds, plaque formation was significantly reduced by more than 80% when HSV-1 was preincubated with p-cymene. However, no inhibitory effect could be observed when the compounds were added to the cells prior to infection with HSV-1 or after the adsorption period. CONCLUSION These results indicate that compounds affected HSV-1 mostly before adsorption and might interact with the viral envelope. Thymol exhibited a high selectivity index and seems to be a promising candidate for topical therapeutic application as antiviral agent for treatment of herpetic infections.

Abstract
The aim of the present study was to investigate the effect of L-carnitine (LC) addition during either IVM or IVC on the developmental potential of camel oocytes. In Experiment 1; camel oocytes were matured in the absence (control) or presence of different concentrations of LC (0.25 mg, 0.5 mg, 0.75 mg and 1 mg/ml) for 30 h followed by in vitro fertilization and culture up to blastocyst stage. Our results demonstrated that oocytes treated with 0.5 mg/ml LC showed higher (P < 0.05) rates of maturation (74.7%) and fertilization (62.2%) compared with control group, 0.25 and 1 mg/ml of LC (60.2, 63.9, 59.7; 46.2, 48.7, 47.6%, respectively). Addition of 0.5 mg/ml of LC to IVM medium improved the rates of cleavage and embryo development (morula and blastocyst) than those obtained in the control group, 0.25 and 1 mg/ml of LC. No significant differences were noticed between 0.5 and 0.75 mg/ml of LC supplemented groups in term of maturation, fertilization and culture. In Experiment 2; zygotes resulting from in vitro matured (without LC) and fertilized were cultured in embryo culture medium supplemented with different concentrations of LC (0.25 mg, 0.5 mg, 0.75 mg and 1 mg/ml) or without LC (control). Also, the results showed a higher developmental rates to morula and blastocyst stages while adding L-carnitine at a level of 0.5 or 0.75 mg/ml concentration in the culture medium during IVC when compared with other groups. In conclusion, the results demonstrated the usefulness of L-carnitine supplementation at the level of 0.5 mg/ml during IVM or IVC after on the developmental potential of camel oocytes.

Abstract
The aging process is associated with a decline in mitochondrial functions. Mitochondria dysfunction is involved in initiation and progression of many health problems including neuromuscular, metabolic and cardiovascular diseases. It is well known that endurance exercise improves mitochondrial function, especially in the elderly. However, recent studies have demonstrated that resistance training lead also to substantial increases in mitochondrial function in skeletal muscle. A comprehensive understanding of the cellular mechanisms involved in the skeletal muscle mitochondrial adaptations to exercise training in healthy elderly subjects, can help practitioners to design and prescribe more effective exercise trainings.

Abstract
The limited effectiveness of the conventional methods for cancer treatment makes the researchers to find novel safe and effective therapeutic strategies. One of these strategies is to use small interfering RNAs (siRNAs). A major challenge here is the siRNA delivery into the cells. The purpose of this study was to design and prepare a biocompatible, biodegradable, and safe nanosized particle for siRNA delivery into human breast cancer MCF-7 and leukemia K562 cells. Chemically synthesized magnetic nanoparticles containing polyethyleneglycol-lactate polymer (PEG-LAC), chitosan, and polyethyleneimine (PEI) were successfully prepared and used as a gene delivery vehicle. The nanoparticles were characterized by Fourier transform infrared spectroscopy and zeta potential. The Fe3O4-PEG-LAC-chitosan-PEI nanoparticle showed efficient and stable survivin siRNA loading in gel retardation assay. The cytotoxicity of the prepared nanoparticle was studied using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay and was compared with that of mitoxantrone (MTX) in combination with the prepared siRNA delivery system to evaluate the possible synergic effect of MTX and survivin siRNA. The nanoparticles with and without noncomplementary siRNA showed low toxicity against both cell lines; however, a twofold decrease was observed in cell survival percent after MTX addition to MCF-7 cells treated with either nanoparticle itself or complexed with noncomplementary siRNA. While survivin siRNA nanoplex caused threefold decrease in the cell survival percent, its combination with MTX did not result in a significant increase in the cytotoxic effect. Therefore, Fe3O4-PEG-LAC-chitosan-PEI nanoparticle should be considered as a potential carrier for enhanced survivin siRNA delivery into MCF-7 and K562 cells.

Abstract
Saddle spinal is a reliable method for control of pain during labor. This method has rapid onset and causes complete sensory block without significant influence on motor neurons.Our goal was to compare the analgesic efficacy and side effects of pethidine and sufentanil via saddle spinal administration during labor.600 parturients requesting analgesia were randomly divided into 2 groups. First group was composed of 300 patients received 0.4 mg/kg pethidine and the second group was composed of 300 patients received 0.1 μg/kg sufentanil. Then, analgesia according to Visual Analogue Scale (VAS), itching, nausea, apnea and urinary retention were examined between 2 groups.VAS=3 was noted in both groups. Equal rate of apnea was seen in both groups. Patients received pethidine showed significantly a higher rate of nausea compared with sufentanil group (P<0.0001). Pruritus was significantly higher in patients received sufantanil (P<0.0001).Our findings suggest that saddle spinal by pethidine or sufentanil causes a considerable analgesia for labor. Proper management of the untoward effects of this method may introduce it as a safe and low-cost method for painless labor.
