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.
