Abstract
BACKGROUND AND PURPOSE The use of dry needling (DN) with other treatments may be more beneficial in managing post-stroke spasticity. We report the effects of DN plus exercise therapy (ET) on wrist flexor spasticity. PATIENT PRESENTATION The patient was a 45-year-old man with an 8-year history of stroke. The outcome measures included the Modified Modified Ashworth Scale (MMAS), Hmax/Mmax ratio, H-reflex latency, Action Research Arm Test (ARAT), Fugl-Meyer Assessment (FMA), and range of motion (ROM) which were assessed before (T1), after (T2), and after 3-week follow-up (T3). CONCLUSION The MMAS was improved at T2 from "3" to "2". The Hmax/Mmax decreased from 0.77 to 0.53 at T3. The H-reflex latency increased from 15.4 ms to 18.5 ms at T3. The wrist active and passive ROM increased ∼30° and ∼20° at T2, respectively. A 4-session DN plus ET may improve spasticity and ROM. No meaningful improvement was observed in function.

Abstract
Biologics are tremendously efficacious biological molecules that have enabled the treatment of many life-threatening diseases, which have previously been hard to treat. Biosimilars, also known as "follow-on biologics", are highly similar versions of another already approved biologic, called the Reference Product. The European Union has been a pioneer in the regulation of biosimilars. WHO guideline on evaluation of biosimilars published in 2009 was an important landmark in biosimilar regulations worldwide, and several countries have adopted its principles in the development of their own regulatory pathway for the approval of biosimilars. Most countries in the Middle East North Africa (MENA) region still lack official and scientific guidelines for biosimilar approval pathways. This article explores the regulatory situation of biosimilar registration pathways in Algeria and describes the progress made and the regulatory landscape changes for biosimilars in Algeria during the past ten years. Our findings indicate that the development of biosimilar regulation in Algeria went through three major phases between 2006 and 2021, during which there has been much progress in drafting guidance documents for biosimilars. Since 2016, Algeria has used the EMA, FDA and WHO guidelines as the basis for approval of several biosimilars and no national guidelines or regulations have been adopted to date. Additionally, there has been no regulation on substitution/interchangeability. The Algerian regulatory authority has gained considerable experience with approval and use of increasingly complex biosimilars over the past 5 years and has the potential to create its own biosimilar-specific regulatory pathway in the near future.

Abstract
Introduction: One of the popular questionnaires for screening neuropathic pain is the DN4 (Douleur Neuropathique 4) which has been translated into many languages and validated in different populations. So, we wanted to determine the Persian version of this questionnaire’s reliability and validity to differentiate neuropathic pain from other painful non-neuropathic conditions. Methods: This cross-sectional study was conducted on 120 patients who suffered from chronic pain referred to the Physical Medicine and Rehabilitation Department at the three great referral hospitals in Tehran, Iran in 2016. In this study, a modified version of DN4 was used to validate adding a question related to the appearance of pain in an especial joint and adding visual analogue scaling (VAS) score in each item. Results: The modified DN4 questionnaire had high reliability for assessing neuropathic pain with the Cronbach’s alpha coefficient of 0.874. The correlation coefficients obtained by the retest intra-class correlation test ranged from 0.650 to 0.941. Also, the internal consistency of Spearman’s R coefficients ranged from 0.482 to 0.904. Test-retest reliability analysis also showed a higher intraclass correlation (ICC) value in the neuropathic than non-neuropathic pain group (0.85 vs0.73). The modified DN4 questionnaire could effectively discriminate neuropathic pain from non-neuropathic pain with the area under the curve (ROC) of 0.989 (95% CI: 971–1000, P < 0.001). The best cutoff value for the modified DN4 questionnaire to diagnose neuropathic pain was 5, yielding a sensitivity of 98.3% and a specificity of 90.3%. Conclusion: Applying the new modified Persian version of DN4 achieved by adding a VAS score and a new question related to the appearance of pain in an especial joint led to high reliability and validity for this tool to discriminate neuropathic from non-neuropathic pain.

Abstract
The current study aimed to investigate the potential of carbon nanofibers to promote peripheral nerve regeneration. The carbon nanofiber-imbedded scaffolds were produced from polycaprolactone and carbon nanofibers using thermally induced phase separation method. Electrospinning technique was utilized to fabricate polycaprolactone/collagen nanofibrous sheets. The incorporation of carbon nanofibers into polycaprolactone's matrix significantly reduced its electrical resistance from 4.3 × 109 ± 0.34 × 109 Ω to 8.7 × 104 ± 1.2 × 104 Ω. Further in vitro studies showed that polycaprolactone/carbon nanofiber scaffolds had the porosity of 82.9 ± 3.7% and degradation rate of 1.84 ± 0.37% after 30 days and 3.58 ± 0.39% after 60 days. The fabricated scaffolds were favorable for PC-12 cells attachment and proliferation. Neural guidance channels were produced from the polycaprolactone/carbon nanofiber composites using water jet cutter machine then incorporated with PCL/collagen nanofibrous sheets. The composites were implanted into severed rat sciatic nerve. After 12 weeks, the results of histopathological examinations and functional analysis proved that conductive conduit out-performed the non-conductive type and induced no toxicity or immunogenic reactions, suggesting its potential applicability to treat peripheral nerve damage in the clinic.

Abstract
OBJECTIVE Peripheral nerve injuries comprise significant portion of the nervous system injuries. Although peripheral nerves show some capacity of regeneration after injury, the extent of regeneration is not remarkable. The present study aimes to evaluate the regeneration of transected sciatic nerve by a therapeutic value of dexamethasone (DEX) associated with cell therapy (Cell) and biodegradable membrane (Mem) in rat. METHODS Male Wistar rats (n = 42, 180-200g) were randomly divided into control (Ctrl), Membrane+ Cell, Mem, DEX, DEX+ Cell, DEX+ Mem and DEX+ Cell+ Mem groups. Functional recovery was evaluated at 2, 4, 6, 8 and 12 weeks after surgery using sciatic functional index (SFI), withdrawal reflex latency (WRL) test, electrophysiological and histological analyses. RESULTS The rats in the DEX+ Cell+ Mem-treated group showed a significant improvement in SFI, WRL and electrophysiological findings during the 2nd to 12th weeks after surgery. In addition, histomorphological findings showed a significant improvement in the DEX+ Cell+ Memtreated group, at 12 weeks after surgery. DISCUSSION Taken together, use of DEX associated with cell and biodegradable membrane could improve functional and histomorphological properties of the sciatic nerve after injury.

Abstract
Purpose To investigate the state of dark adaptation and macular blood flow in different forms of glaucoma. Methods Eighteen eyes of 18 patients with primary open-angle glaucoma, 14 eyes of 14 patients with pseudoexfoliation glaucoma, and 10 eyes of 10 patients with childhood glaucoma (CG) were examined by means of dark adaptometry, scanning-laser retinal flowmetry, and retinal tomography. Results All glaucomatous eyes had comparable optic disc excavation (one-way ANOVA, p = 0.138). Eyes with CG had significantly lower best-corrected visual acuity than the other groups (Tukey, all p < 0.0001). Macular perfusion was comparable in all three groups (one - way ANOVA, p = 0.08). The delay in rod-cone break time in the CG group was significantly higher than in the other groups (Tukey, all p < 0.0001). The scotopic sensitivity threshold in the CG group was significantly greater than in the other groups (Tukey, all p < 0.01). Conclusion This underlying dysfunction of dark adaptation may contribute, at least to some extent, to the decreased visual perception observed in patients with CG.

Abstract
OBJECTIVES Stem cell therapy is considered to be a suitable alternative in treatment of a number of diseases. However, there are challenges in their clinical application in cell therapy, such as to reduce survival and loss of transplanted stem cells. It seems that chemical and pharmacological preconditioning enhances their therapeutic efficacy. In this study, we investigated effects of all-trans retinoic acid (ATRA) on survival, angiogenesis and migration of mesenchymal stem cells (MSCs) in vitro and in a wound-healing model. MATERIALS AND METHODS MSCs were treated with a variety of concentrations of ATRA, and mRNA expression of cyclo-oxygenase-2 (COX-2), hypoxia-inducible factor-1 (HIF-1), C-X-C chemokine receptor type 4 (CXCR4), C-C chemokine receptor type 2 (CCR2), vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2) and Ang-4 were examined by qRT-PCR. Prostaglandin E2 (PGE2) levels were measured using an ELISA kit and MSC angiogenic potential was evaluated using three-dimensional tube formation assay. Finally, benefit of ATRA-treated MSCs in wound healing was determined with a rat excisional wound model. RESULTS In ATRA-treated MSCs, expressions of COX-2, HIF-1, CXCR4, CCR2, VEGF, Ang-2 and Ang-4 increased compared to control groups. Overexpression of the related genes was reversed by celecoxib, a selective COX-2 inhibitor. Tube formation and in vivo wound healing of ATRA-treated MSCs were also significantly enhanced compared to untreated MSCs. CONCLUSION Pre-conditioning of MSCs with ATRA increased efficacy of cell therapy by activation of survival signalling pathways, trophic factors and release of pro-angiogenic molecules.

Abstract
BACKGROUND Spasticity is a common complication after stroke. Dry needling (DN) is suggested as a novel method for treatment of muscle spasticity. OBJECTIVE To explore the effects of DN on wrist flexors spasticity poststroke. METHODS A single group, pretest-posttest clinical trial was used. Twenty nine patients with stroke (16 male; mean age 54.3 years) were tested at baseline (T0), immediately after DN (T1), and one hour after DN (T2). DN was applied for flexor carpi radialis (FCR) and flexor carpi ulnaris on the affected arm for single session, one minute per muscle. The Modified Modified Ashworth Scale (MMAS), passive resistance force, wrist active and passive range of motion, Box and Block Test, and FCR H-reflex were outcome measures. RESULTS Significant reductions in MMAS scores were seen both immediately after DN and at 1-hour follow-up (median 2 at T0 to 1 at T1 and T2). There were significant improvements in other measures between the baseline values at T0 and those recorded immediately after the DN at T1 or one hour later at T2. CONCLUSIONS This study suggests that DN reduced wrist flexors spasticity and alpha motor neuron excitability in patients with stroke, and improvements persisted for one hour after DN.

Abstract
The increasing availability of large collections of chemical structures and associated experimental data provides an opportunity to build robust QSAR models for applications in different fields. One common concern is the quality of both the chemical structure information and associated experimental data. Here we describe the development of an automated KNIME workflow to curate and correct errors in the structure and identity of chemicals using the publicly available PHYSPROP physicochemical properties and environmental fate datasets. The workflow first assembles structure-identity pairs using up to four provided chemical identifiers, including chemical name, CASRNs, SMILES, and MolBlock. Problems detected included errors and mismatches in chemical structure formats, identifiers and various structure validation issues, including hypervalency and stereochemistry descriptions. Subsequently, a machine learning procedure was applied to evaluate the impact of this curation process. The performance of QSAR models built on only the highest-quality subset of the original dataset was compared with the larger curated and corrected dataset. The latter showed statistically improved predictive performance. The final workflow was used to curate the full list of PHYSPROP datasets, and is being made publicly available for further usage and integration by the scientific community.

Abstract
BACKGROUND The aim of this study was to determine the effects of amniotic membrane impregnated with betamethasone on regeneration of transected sciatic nerve injury in adult albino Wister rats. METHODS In this research, 42 male adult rats were divided into six equal groups. 1) Normal (intact) group: healthy rats without any injury; 2) CONTROL GROUP: sciatic nerve was cut and sutured; 3) Sham group: 0.2 mL culture medium was injected on the epineurium in the injury; 4) Amniotic membrane group (AM): Acellular amniotic membrane was used around the damaged sciatic nerve; 5) Betamethasone group (B): 0.2 mL Betamethasone (4 mg/mL) was injected in the site of damaged nerve and 6) Amniotic membrane group and Betamethasone (AM/B) group: Acellular amniotic membrane impregnated with 0.2 mL betamethasone was used around the damaged sciatic nerve. The rate of recovery was studied by Sciatic Functional Index (SFI), withdrawal reflex latency (WRL) test and electroctrophysiological assessments at 2, 4, 6 and 8 weeks after surgery. Histological assessment was done 8 weeks after surgery. RESULTS At 8 weeks after surgery, SFI, WRL test and electrophysiological values in AM/B group were significantly improved compared to control and sham groups (P < 0.05). Histological results showed improvement in therapeutic groups, especially AM/B group compared to control and sham groups and other therapeutic groups (P < 0.05). CONCLUSION The present study showed the positive effects of Amniotic membrane and Betamethasone on nerve regeneration of transected sciatic nerve in a rat model.

Abstract
Introduction: Spinal cord injury (SCI) involves a primary trauma and secondary cellular processes that can lead to severe damage to the nervous system, resulting in long-term spinal deficits. At the cellular level, SCI causes astrogliosis, of which glial fibrillary acidic protein (GFAP) is a major index. Objective: The aim of this study was to investigate the neuroprotective effects of Lavandula angustifolia (Lav) on the repair of spinal cord injuries in Wistar rats. Materials and Methods: Forty-five female rats were randomly divided into six groups of seven rats each: the intact, sham, control (SCI), Lav 100, Lav 200, and Lav 400 groups. Every week after SCI onset, all animals were evaluated for behavior outcomes by the Basso, Beattie, and Bresnahan (BBB) score. H&E staining was performed to examine the lesions post-injury. GFAP expression was assessed for astrogliosis. Somatosensory evoked potential (SEP) testing was performed to detect the recovery of neural conduction. Results: BBB scores were significantly increased and delayed responses on sensory tests were significantly decreased in the Lav 200 and Lav 400 groups compared to the control group. The greatest decrease of GFAP was evident in the Lav 200 and Lav 400 groups. EMG results showed significant improvement in the hindlimbs in the Lav 200 and Lav 400 groups compared to the control group. Cavity areas significantly decreased and the number of ventral motor neurons significantly increased in the Lav 200 and Lav 400 groups. Conclusion: Lav at doses of 200 and 400 mg/kg can promote structural and functional recovery after SCI. The neuroprotective effects of L. angustifolia can lead to improvement in the contusive model of SCI in Wistar rats.

Abstract
OBJECTIVES Both excessive and insufficient angiogenesis are associated with progression of diabetic complications, of which poor angiogenesis is an important feature. Currently, adipose-derived stem cells (ADSCs) are considered to be a promising source to aid therapeutic neovascularization. However, functionality of these cells is impaired by diabetes which can result from a defect in hypoxia-inducible factor-1 (HIF-1), a key mediator involved in neovascularization. In the current study, we sought to explore effectiveness of pharmacological priming with deferoxamine (DFO) as a hypoxia mimetic agent, to restore the compromised angiogenic pathway, with the aid of ADSCs derived from streptozotocin (STZ)-induced type 1 diabetic rats ('diabetic ADSCs'). MATERIALS AND METHODS Diabetic ADSCs were treated with DFO and compared to normal and non-treated diabetic ADSCs for expression of HIF-1α, VEGF, FGF-2 and SDF-1, at mRNA and protein levels, using qRT-PCR, western blotting and ELISA assay. Activity of matrix metalloproteinases -2 and -9 were measured using a gelatin zymography assay. Angiogenic potential of conditioned media derived from normal, DFO-treated and non-treated diabetic ADSCs were determined by in vitro (in HUVECs) and in vivo experiments including scratch assay, three-dimensional tube formation testing and surgical wound healing models. RESULTS DFO remarkably enhanced expression of noted genes by mRNA and protein levels and restored activity of matrix metalloproteinases -2 and -9. Compromised angiogenic potential of conditioned medium derived from diabetic ADSCs was restored by DFO both in vitro and in vivo experiments. CONCLUSION DFO preconditioning restored neovascularization potential of ADSCs derived from diabetic rats by affecting the HIF-1α pathway.

Abstract
Recently, several studies have shown that the metal-fluoroquinolone complexes have more antibacterial and cytotoxic effects in comparison with free fluoroquinolones. These results may introduce new drugs for chemotherapy with fewer side effects. In this work a bidentated zinc (II) complex with ofloxacin (OZC) was synthesized and cytotoxicity activities and DNA binding of the resulted complex was studied. The in-vitro anti proliferative and cytotoxic effects of the free ofloxacin (OFL) and OZC against MCF-7, CaCo2 and SKNMC cell lines were tested by using Trypan blue and lactate dehyrogenase (LDH) assay methods. Results revealed that the OZC exhibits better anti proliferative and cytotoxic activities as compared with the OFL. This may be due to the more interaction of OZC with DNA. Therefore, the interaction of OZC with DNA was investigated by using voltammetry, UV-Vis, fluorescence, FT-IR and circular dichroism spectroscopy methods, and the equilibrium binding constant (Kb), binding site size, and thermodynamic parameters were measured. The results revealed that the OZC interacts with DNA via two modes: electrostatic and outside hydrogen binding. The proposed DNA binding modes may support the greater in-vitro cytotoxicity of OZC compared to OFL alone.

Abstract
BACKGROUND Spasticity is a common impairment following upper motor neuron lesions such as stroke. The appropriate measurement of muscle spasticity using validated tools to evaluate the outcome of therapies is important in clinical and research settings. OBJECTIVE To determine the concurrent criterion-related validity of the Modified Tardieu Scale (MTS) in assessing poststroke wrist flexor muscle spasticity based on its correlation with H-reflex tests. METHODS A total of 20 adult patients poststroke underwent clinical and electrophysiological assessment of wrist flexor muscle spasticity on the affected side. The primary outcome measures were: R2-R1 of the MTS; and the H-reflex indices of Hmax/Mmax ratio and Hslp/Mslp ratio. The Hslp and the latency of H-reflex were also measured. RESULTS Correlations tests did not reveal significant associations between the clinical and H-reflex tests. CONCLUSIONS This study suggests that the MTS may not be a valid tool to evaluate muscle spasticity in this sample of patients after stroke.

Abstract
INTRODUCTION Transplantation of bone marrow stromal cells (BMSCs) or Schwann cells (SCs) can increase axonal regeneration in peripheral nerve injuries. Based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury. We pursued to evaluate the effects of BMSCs and SCs co-transplantation on the functional recovery after sciatic nerve injury in rat. METHODS In this experimental research, adult male Wistar rats (n = 32, 250-300g) were used, BMSCs and SCs were cultured, and the SCs were confirmed with anti S100 antibody. Rats were randomly divided into 4 groups (n = 8 in each group): 1-control group: silicon tube filled with fibrin gel without cells; 2-BMSCs group: silicon tube filled with fibrin gel seeded with BMSCs; 3-SCs group: silicon tube filled with fibrin gel seeded with SCs and 4-co-transplantation group: silicone tube filled with fibrin gel seeded with BMSCs and SCs. The left sciatic nerve was exposed, a 10 mm segment removed, and a silicone tube interposed into this nerve gap. BMSCs and SCs were transplanted separately or in combination into the gap. BMSCs were labeled with anti-BrdU and SCs were labeled with DiI. After 12 weeks electromyographic and functional assessments were performed and analyzed by one-way analysis of variance (ANOVA). RESULTS Electromyographic and functional assessments showed a significant difference between the experimental groups and controls. Electromyography measures were significantly more favourable in SCs transplantation group as compared to BMSCs transplantation and co-transplantation groups (p < 0.05). Functional assessments showed no statistically significant difference among the BMSCs, SCs and co-transplantation groups (p < 0.05). DISCUSSION Transplantation of BMSCs and SCs separately or in combination have the potential to generate functional recovery after sciatic nerve injury in rat. The electromyography evaluation showed a greater improvement after SCs transplantation than BMSCs or the co-transplantation of BMSCs and SCs.

Abstract
Glaucoma is the main cause of irreversible blindness and intraocular pressure (IOP) is its only modifiable risk factor. The importance of robust lowering of IOP for prevention of glaucoma onset and progression is well established. Although IOP is a dynamic parameter with individual circadian rhythms, current management usually relies on single IOP measurements during regular clinic hours performed a few times a year. Recent technological advances have provided clinicians with tools for continuous IOP monitoring during a 24 hour period in an ambulatory setting. There are two approaches being investigated. The first is permanent IOP monitoring through an implantable sensor and the other is temporary monitoring through a contact lens sensor. In this article, we discuss the shortcomings of the current gold standard for tonometry (Goldmann Applanation Tonometry) and the current experience with the first commercially available continuous 24 hour IOP monitoring technology (SENSIMED Triggerfish®); a telemetric contact lens sensor produced by a Swiss start-up company (Sensimed AG, Lausanne, Switzerland). Recent studies suggest that 24 hour continuous monitoring of IOP can be integrated into clinical practice and have the potential to contribute to the reduction of glaucoma-related vision loss.

Abstract
OBJECTIVES Skin-derived precursors are recognized to be a potentially autologous and accessible source of neural precursor cells for drug screening or cell-based treatments, in many neurological disorders. Thus, it is necessary to investigate appropriate methods for cryopreservation of such human skin-derived precursors (hSKPs). The aim of this study was to evaluate different cryopreservation techniques for retention of hSKPs to discover an optimized protocol. MATERIALS AND METHODS We cryopreserved hSKPs treated with 0%, 10%, 20%, 30% and 40% foetal bovine serum (FBS) and three concentrations of dimethylsulphoxide (DMSO) 5%, 10% and 15%, with two different storage periods in liquid nitrogen (2 days: short-term storage; and 2 months: long-term storage). Then, we assessed survival and proliferation levels of the cells after freeze-thaw processes, by viability measurement and colony-forming assay. For detecting hSKPs, we used immunocytochemistry and RT-PCR assessments. RESULTS Our findings indicated that hSKPs cryopreserved in 5% DMSO without FBS, had better survival and proliferation potentials compared to other working formulations. With various concentrations of cryoprotectants over different time periods, hSKPs retained their differentiation potentiality and were able to differentiate into neurons (NFM and βΙΙΙ tubulin-positive), glial cells (GFAP-positive) and smooth muscle cells (SMA-positive). CONCLUSIONS Results revealed that in only 5% DMSO, hSKPs could be cryopreserved for long-term storage with considerable survival and proliferation levels, without losing multipotency.

Abstract
INTRODUCTION Reliable and valid tools must be used to assess spasticity in clinical practise and research settings. There is a paucity of literature regarding the validity of the Modified Modified Ashworth Scale (MMAS) and the Modified Tardieu Scale (MTS). No study, to date, has been performed to compare the validity of the MMAS and the MTS. This neurophysiological study protocol will compare the validity of the MMAS and the MTS in the assessment of poststroke wrist flexor spasticity. METHODS AND ANALYSIS Thirty-two patients with stroke from the University Rehabilitation clinics will be recruited to participate in this cross-sectional, non-interventional study. All measurements will be taken in the Physical Medicine and Rehabilitation Department of Shafa University Hospital in Tehran, Iran. First, wrist flexor spasticity will be assessed clinically using the MMAS and MTS. The tests will be applied randomly. For the MTS, the components of R1, R2, R2-R1 and quality of muscle reaction will be measured. Second, neurophysiological measures of H-reflex latency, H(max)/M(max) ratio, H(slp) and H(slp)/M(slp) ratio will be collected from the affected side. The results will be analysed using Spearman's ρ test or Pearson's correlation test to determine the validity of the MMAS and the MTS as well as to compare the validity between the MMAS and the MTS. ETHICS AND DISSEMINATION The Research Council, School of Rehabilitation and the Ethics Committee of Tehran University of Medical Sciences (TUMS) approved the study protocol. The study results will be disseminated in peer-reviewed publications and presented at international congresses.

Abstract
PURPOSE To review the ability of current imaging technologies to provide estimates of rates of structural change in glaucoma patients. PATIENTS AND METHODS Review of literature. RESULTS Imaging technologies, such as confocal scanning laser ophthalmoscopy (CSLO), scanning laser polarimetry (SLP), and optical coherence tomography (OCT), provide quantifiable and reproducible measurements of the optic disc and parapapillary retinal nerve fibre layer (RNFL). Rates of change as quantified by the rim area (RA) (for CSLO) and RNFL thickness (for SLP and OCT) are related to glaucoma progression as detected by conventional methods (eg, visual fields and optic disc photography). Evidence shows that rates of RNFL and RA loss are significantly faster in progressing compared with non-progressing glaucoma patients. CONCLUSION Measurements of rates of optic disc and RNFL change are becoming increasingly precise and individualized. Currently available imaging technologies have the ability to detect and quantify progression in glaucoma, and their measurements may be suitable end points in glaucoma clinical trials.

Abstract
PRIMARY OBJECTIVE To determine the extent to which the Brunnstrom recovery stages of upper limb in hemiparetic stroke patients are correlated to neurophysiological measures and the spasticity measure of Modified Modified Ashworth Scale (MMAS). RESEARCH DESIGN A concurrent criterion-related validity study. INTERVENTIONS Not applicable. METHODS AND PROCEDURES Thirty patients (15 men and 15 women; mean ± SD = 58.8 ± 11.5 years) with upper limb spasticity after stroke were recruited. Wrist flexor spasticity was rated using the MMAS. The neurophysiological measures were Hslp/Mslp ratio, H(max)/M(max) ratio and Hslp. MAIN OUTCOMES AND RESULTS There was a significant moderate correlation between the Brunnstrom recovery stages and the neurophysiological measures. The Brunnstrom recovery stages were highly correlated to the MMAS scores (r = -0.81, p < 0.0001). CONCLUSIONS The Brunnstrom recovery stages are moderately correlated with neurophysiological measures and highly correlated with the MMAS regarding the evaluation of motor recovery in stroke patients. The Brunnstrom recovery stages can be used as a valid test for the assessment of patients with post-stroke hemiplegia.

Abstract
PURPOSE To compare the accuracy in measurement of the anterior chamber (AC) angle by anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) in European patients with suspected primary angle closure (PACS), primary angle closure (PAC), or primary angle-closure glaucoma (PACG). DESIGN Cross-sectional study. METHODS In all, 55 eyes of 33 consecutive patients presenting with PACS, PAC, or PACG were examined with AS-OCT, followed by UBM. The trabecular-iris angle (TIA) was measured in all four quadrants. The angle-opening distance (AOD) was measured at 500 microm from the scleral spur. The Bland-Altman method was used for assessing agreement between the two methods. RESULTS The mean (+/-SD) superior TIA was 19.3+/-15.8 degrees in AS-OCT and 15.7+/-15.0 degrees in UBM (P=0.50) and inferior TIA was 17.9+/-12.9 degrees (AS-OCT) and 16.7+/-14.1 degrees (UBM) (P=0.71). The superior AOD(500) was 0.17+/-0.16 mm in UBM and 0.21+/-0.16 mm in AS-OCT (P=0.06). Bland-Altman analysis showed a mean SD of+/-9.4 degrees for superior and inferior TIA and a mean SD of +/-0.10 mm for superior and inferior AOD(500). CONCLUSIONS This comparative study shows that AS-OCT measurements are significantly correlated with UBM measurements but show poor agreement with each other. We do not believe that AS-OCT can replace UBM for the quantitative assessment of the AC angle.

Abstract
BACKGROUND A point mutation at the locus 3243 of the mitonchondrial DNA (mtDNA) is associated with either the MIDD syndrome (maternally inherited diabetes, deafness), the MELAS syndrome (myopathy, encephalitis, lactic acidosis, stroke) or cardiac, digestive, endocrine or exocrine dysfunctions. We report a peculiar maculopathy in two patients with an mtDNA 3243 mutation. HISTORY AND SIGNS Case 1: A visually asymptomatic 40-year-old woman was examined for screening of diabetic retinopathy. Visual acuity was 10 / 10 in both eyes. Case 2: A 54-year-old woman with deafness and diabetes complained of visual loss. Visual acuity was 6 / 10 for the right eye and 0.5 / 10 for the left eye. Both patients exhibited a chorioretinal areolar atrophy. Case 1 was followed over 15 years and exhibited a slow progression of the maculopathy with moderate loss of visual acuity to 6 / 10 in both eyes, but marked handicap from the annular scotoma. THERAPY AND OUTCOME None. CONCLUSION Both patients presented a perimacular annular retinal atrophy. Patients harbouring mtDNA 3243 mutation should be examined for the presence of a maculopathy, even if they are asymptomatic. Conversely, the finding of such a geographic maculopathy should suggest the possibility of a point mutation at the locus 3243 of the mitochondrial DNA, especially in the presences of diabetes mellitus and/or deafness.

Abstract
The Modified Ashworth Scale (MAS) is currently a widely used clinical scale to evaluate muscle spasticity. However, it lacks reliability and the validity, of the MAS as a clinical measure of muscle spasticity has been challenged. The aim of the present study was to examine the validity of the MAS in patients with wrist flexor spasticity after stroke by using the Hslope/Mslope (Hslp/Mslp) ratio as the new index of alpha motoneuron excitability. Twenty-seven adult patients (14 women and 13 men) with first ever stroke resulting in hemiplegia with a mean (SD, range) age of 57.9 (11.6, 37-75) were included in the study. The main outcome measures were the MAS for the clinical assessment of spasticity, and the Hslp/Mslp for the neurophysiological evaluation. There was not a significant correlation between the MAS scores and Hslp/Mslp ratio (r = 0.38, p > 0.05). The mean of the Hslp/Mslp did not show a hierarchical increase with the MAS scores. The findings indicate that the MAS is not a valid and ordinal level measure of muscle spasticity.

There was a significant positive correlation between the MMAS scores and Hslp/Mslp ratio as the new index of alpha motoneurone excitability or traditional index of H(max)/M(max) ratio (r = 0.39, p = 0.04). It is concluded that the MMAS to be a valid measure of spasticity after stroke.

Abstract
Angiogenesis is a complex process during which of new blood vessels are produced from the preexisting blood vessels. Formation and growth of new vessels play an important role in the physiologic process (embryonic growth, tissue repair) and pathologic process (tumor growth, inflammation) for surviving of the tissues. In fact, the development of tumors is depended upon new vessel formation through which the tumor is provided with nutrient and oxygen. In this research, the role ofplasminogen conformation with MC2B8 mAb (an antibody directed against C-terminal part of plasminogen) in clot lysis and angiogenesis is observed. In experimental model of angiogenesis, beads, covered with endothelial cells of bone marrow capillaries, are the source of endothelial cells. It coated in three-dimensional structure to be provided through fibrin gel. Different titers of monoclonal antibody (30-480 microg mL(-1)) MC2B8 were added in fibrin gel. 3-5 days after culturing of endothelial cells, growth and migration was seen as the result of capillary formation MC2B8 mAb delayed clot lysis and inhibited angiogenesis at the concentration of 240 microg mL(-1). Present findings suggest that these effects on capillary tube formation and clot lysis caused blockage or conformational changes in plasminogen epitopes involved in angiogenesis and fibrinolysis.

Abstract
The Modified Ashworth Scale (MAS) is the most widely used clinical test for the measurement of muscle spasticity. This scale that suffers from limitations and lack of reliability and validity has recently been remodified. The aim of the present study is to investigate the criterion validity of the new Modified MAS(MMAS) in the upper limb in post-stroke hemiplegia, using the Hslope/Mslope (Hslp/Mslp) as a novel index of alpha motor neuron excitability. Prior to the validity study, the reliability of the MMAS was evaluated in 30 hemiplegic patients. The raters agreed on 23 patients (0. 76%). The MMAS had good inter-rater reliability (K= 0.63, SE = 0.11, p < 0.001) for the assessment of wrist flexors spasticity in hemiplegic patients. 12 adult patients (7 women and 5 men) with first ever stroke resulting in hemiplegia with a mean age of 58.9 +/- 11.9 years (range, 37-73) were included in the validity study. The outcome measures were the MMAS for the clinical assessment of spasticity, and the HslopelMslope and the Hmax/Mmax ratio for the electrophysiological evaluation. The results showed an increase in mean rank of Hslp / Mslp in patients with a score of 1, 2 or 3 on the MMAS. However, the difference among the groups was not significant (p > 0.05). There was also no relationship between the clinical scale of MMAS and either the traditional [Hmax / Mmax ratio (r = -0.06)] or the new index [Hslp / Mslp (r = 0.24)] of spinal excitability. This preliminary study recruited a small number of patients, and failed to confirm a linear correlation between these variables. A study with a large number of patients is suggested to clarify the outcome.

Abstract
This phase II study evaluated the activity and toxicity of gemcitabine plus cisplatin as first-line treatment of patients with advanced ovarian cancer. Chemonaive patients >/=60-year-old with FIGO stage IIIC or IV epithelial ovarian carcinoma were enrolled. Patients received cisplatin 75 mg /m2 on day 1 and gemcitabine 1250 mg /m2 on day 1 (before cisplatin) and day 8 of a 21-day cycle. Of 44 female patients (median age, 70 years), 72.7% had stage IIIC disease and 67.4% had a Karnofsky performance status >/=80. Of the 37 response-evaluable patients (35 with measurable lesion[s] >/=2 cm), there were seven (18.9%) pathologic complete responses, two (5.4%) pathologic partial responses, two (5.4%) clinical complete responses, and 12 (32.4%) clinical partial responses, for an overall response rate of 62.2% (95% CI, 44.8%-77.5%), and a pathologic response rate of 24.3% (95% CI, 11.8%-41.2%). Median survival was 27.7 months (95% CI, 14.3-40.8 months). Grade 3/4 neutropenia and thrombocytopenia occurred in 59.5% and 30.2% of patients, respectively, with neutropenic fever in one patient. Grade 3 nausea /vomiting and alopecia occurred in 25.6% and 9.5% of patients, respectively. We conclude that gemcitabine plus cisplatin is active and feasible as first-line treatment of advanced epithelial ovarian cancer in patients >/=60 years. Further clinical trials adding gemcitabine to current standard, first-line treatment seem warranted in younger as well as older patients.

Abstract
BACKGROUND Both gemcitabine and etoposide are active in the treatment of small-cell lung cancer (SCLC), and are characterised by mild toxicity profiles. The combination of both drugs was found to be feasible and active in a phase I dose-finding study in solid tumours. Therefore, a phase II trial was initiated to examine the activity and toxicity of this schedule in extensive disease SCLC. PATIENTS AND METHODS Forty-two chemo-naïve extensive disease SCLC patients were enrolled to receive gemcitabine 1000 mg/m2, days 1, 8 and 15, and etoposide 80 mg/m2, days 8, 9 and 10 of a 28-day cycle. RESULTS Thirty-seven patients were evaluable for efficacy (five received less than one cycle). No complete responses were observed, but partial responses were seen in 17 patients, yielding an overall response rate of 46%. The median duration of response was 5.8 months. Disease stabilisation was obtained in another 10 patients (27%). The median survival of the 37 protocol-qualified patients was 10.5 months (95% confidence interval (CI): 7.5-12.0). The levels of WHO grade 3 and 4 toxicities were low and clinically manageable. CONCLUSION In comparison with standard platinum-based regimens, this combination of gemcitabine and etoposide resulted in a somewhat lower response rate, but a similar median survival time. Haematological toxicity was more pronounced than expected from the toxicity data of each agent individually. However, because of its mild non-haematological toxicity, and its ability to be administered in an outpatient setting, this combination provides a reasonable palliative option for patients with extensive disease SCLC.
