Objective. The objective of this study was to explore the effectiveness of date palm pollen (DPP) in the prevention and treatment of oral mucositis induced by radiation and chemotherapy. Methods. Twenty subjects with varying head and neck cancers were enrolled. Ten subjects were treated with DPP administered orally (2 g daily for 42 days) as a swish and swallow suspension, and 10 control subjects received the facility standard of care. Objective oral assessments using the Oral Mucositis Assessment Scale (OMAS) were conducted at baseline and while the subjects were on treatment. Study subjects also evaluated the treatment impact by visual analog scales for severity of mouth pain and ability to swallow. Results. The results obtained demonstrate a statistically significant difference between the mean OMAS score in the DPP treatment group and the control group. Symptoms such as impairment of solid food intake observed with the control group were not observed in the DPP-treated group following the treatment. Reduction of mucositis severity of pain and ability to swallow were statistically significant in the DPP-treated group. Conclusion. DPP treatment reduced the incidence of mouth pain and oral ulcers that often require modifications to soft/liquid diet. The complex mixture of bioactive constituents contained in DPP may have protected the oral mucosa by blocking oxidative free radicals, preventing DNA damage, and neutralizing inflammatory reactions. Further randomized controlled studies are needed to validate DPP efficacy in the broader management of chemotherapy- and radiation-induced mucositis.

Date Palm Pollen

Natural extract from plant-based has grown in popularity as protective properties in extender for preserving animal semen. Date palm pollen grain (DPPG) is commercially used for male fertility by enhancing sperm count, motility and DNA quality because DPPG contains flavonoids. Thus, the present study aimed to evaluate the effect of a) extender supplementation with different concentration of DPPG on sperm motility, viability and membrane integrity b) different preservation storage of chilled and frozen bovine semen after seven days. The semen was collected through electrical stimulation and assigned to four treatment groups. The semen were diluted in Tris citric fructose egg yolk (TCFY) diluent (control group; CG) or supplemented with DPPG with different concentration (G1 = 2%, G2 = 4% and G3 = 6% in 20 mg DPPG/40 mL of Tris citric fructose (TCF). Semen samples were chilled (experiment 1) in the refrigerator (4°C) for seven days and cryopreserved in liquid nitrogen (experiment 2) prior to dilution to four treatments. The samples were thawed in a water bath (37 °C) and analysed for motility, membrane integrity and viability by conventional laboratory methods. No significant difference was observed among treatment groups in experiment 1. However, in the second experiment, the addition of 6% DPPG resulted significantly higher (p<0.05) in sperm viability compared to control groups (71.25±1.04) vs (56.47±4.69). The supplementation of 6% DPPG showed the ability to protect the viability of bovine sperm, respectively.

ABSTRACT The polysaccharide fucoidin is a selectin blocker that inhibits leukocyte recruitment into the cerebrospinal fluid (CSF) during experimental pneumococcal meningitis. In the present study, the effect of fucoidin treatment on the release of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), and IL-8 into the CSF was investigated. Rabbits (n = 7) were treated intravenously with 10 mg of fucoidin/kg of body weight every second hour starting 4 h after intracisternal inoculation of ∼106 CFU of Streptococcus pneumoniae type 3 (untreated control group, n = 7). CSF samples were obtained every second hour during a 16-h study period. Treatment with fucoidin caused a consistent and significant decrease in CSF IL-1 levels (in picograms per milliliter) between 12 and 16 h (0 versus 170, 0 versus 526, and 60 versus 1,467, respectively;P < 0.02). A less consistent decrease in CSF TNF-α levels was observed in the fucoidin-treated group, but with no significant difference between the two groups (P > 0.05). In contrast, there was no attenuation in CSF IL-8 levels. Indeed, there was a significant increase in CSF IL-8 levels (in picograms per milliliter) in the fucoidin-treated group at 10 and 12 h (921 versus 574 and 1,397 versus 569, respectively;P < 0.09). In conclusion, our results suggest that blood-derived leukocytes mainly are responsible for the release of IL-1 and to some degree TNF-α into the CSF during pneumococcal meningitis, whereas IL-8 may be produced by local cells within the brain.

Aims. The aim of this study was to assess the efficacy and safety of timolol in the treatment of myopic regression after laser in situ keratomileusis (LASIK).Methods. We searched MEDLINE, CENTRAL, EMBASE, China National Knowledge Infrastructure (CNKI), and Chinese Biological Medicine (CBM) from the inception to July 2015 for relevant randomized controlled trials that examined timolol therapy for myopic regression. The methodological quality of the studies included was assessed using the Revman 5.3 software.Results. We included six clinical trials involving 483 eyes in this review, including 246 eyes in treated group and 237 eyes in controlled group. We observed statistically significant improvements on the postoperative SE in the 3 months. However, the change of CCT was not statistically different between the control group and the experimental group. There were fewer cases of IOP, UDVA, and CDVA in treated group having significant difference from the controlled group.Conclusions. Topical timolol could be an effective treatment for reduction of myopic regression especially the spherical errors after myopic LASIK. Further RCTs with larger sample sizes for these trials are warranted to determine the efficacy and limitation for myopic regression after LASIK.

Gastric Mucosa Damage

Although cisplatin is a potent anticancer drug, it instigates oxidative and pro-inflammatory reactions that pose significant and distressing clinical symptoms. Therefore, this study investigated the effects of vitamin C and (or) l-carnitine on cisplatin-induced gastric mucosa damage in rat. The rats were allocated into 6 groups (n = 5). The control group received distilled water, while the treatment groups received cisplatin alone (CIP), or cisplatin with vitamin C, l-carnitine, or their combination. Cisplatin caused disruption of the gastric mucosa histoarchitecture and altered the mucus barrier function. Moreover, the stomach tissue of the CIP-treated group showed increased levels of oxidative stress markers (malondialdehyde and H2O2) and decreased activities of antioxidant (superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase) and non-antioxidant (reduced glutathione) enzymes. These deleterious events were accompanied with significant increases in pro-inflammatory cytokines and inflammatory infiltration markers, myeloperoxidase and inducible nitric oxide synthase. However, the administration of both vitamin C and l-carnitine, and not either of the two showed additive effects in attenuating the adverse effects of cisplatin. The histological results agreed with the biochemical assays. The study concluded that the combined administration of vitamin C and l-carnitine, but not the single therapy, could prevent the adverse effects of cisplatin on gastric tissue.

     The present study was undertaken to evaluate the effect of aqueous extract of Date Palm Pollen DPP on the testicular function and serum testosterone, FSH and LH hormones value. Thirty five male rats were divided randomly into five equal groups. Group 1: received 0.5 ml of distilled water (control group), group 2: was treated orally 0.250 p.p.m of sodium florid (NaF) (with volume of 0.5 ml / rat), Group 3: was treated with 0.250 p.p.m of NaF and 50 mg/kg. B.W. of DPP extract (0.5ml D.W \rat), Group 4: was treated with 0.250 p.p.m of NaF and 100 mg/kg. B.W. of DPP extract and Group 5: was treated with 0.250 p.p.m of NaF and 150 mg/kg. B.W. of DPP extract. The results showed  significant (P< 0.05) decrease in sperm concentration, motility and significant (P< 0.05) increases in dead and abnormal sperm in the group 2 in comparison to control, while all groups of  DPP extract showed significant (P< 0.05) increase in  sperm concentration, motility and decrease in dead and abnormal sperm. Maximum effect was observed in animals treated with a dose of 150 mg/kg of DPP extract, also the results revealed significant (P< 0.05) increase in testosterone, FSH and LH hormones in groups treated with DDP in comparison to G1andG2. Male rats received DPP for 50 days showed significant (P< 0.05) increases in body and testes weight as compared to G1andG2. In conclusion the results revealed that the aqueous extract of DPP pollen can be used as a sex enhancer and seems to cure male infertility.

ABSTRACT A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per animal and feed conversion. The slaughter of the animals and the assessment of the carcass and meat quality and hormone levels were carried out in a slaughterhouse and the municipality of Campinas (SP). The study demonstrated that the use of NSS was a viable alternative in relation to the zootechnical performance and the carcass quality. In relation to the meat quality there was no significant difference in the majority of the assessed parameters.

AbstractSeveral studies have shown microRNAs (miRNAs) could regulate the placental development, yet the role and mechanism of miRNAs in the development of non-diabetic macrosomia (NDFMS) remains unclear. The key miRNA that abnormal expressed in NDFMS placentas was screened out by miRNA microarray and verified using qRT-PCR in 91 subjects. The effects of the key miRNA were verified by proliferation assay and invasion assay in HTR-8/SVneo cell, and also in pregnant C57BL/6J mice. miR-141-3p was determined as the key miRNA with the most significant difference, which could promote the proliferation and invasion by regulating the expression of target gene PLAG1. Overexpression of PLAG1 could reverse the effect of cell proliferation and invasion ability caused by miR-141-3p overexpression. Significant difference in fetal birth weight was observed between the control group and treated group with miR-141-3p agomir in late pregnancy, but not in early pregnancy. This study revealed miR-141-3p could increase the proliferation of placenta to participate in the occurrence and development of NDFMS through regulating PLAG1 expression.

Radioimmunoassay Method

A radioimmunoassay method for antithrombin III (ATIII) was developed in order to detect the AT III levels correctly in plasma and tissues and the effect of heparin infusion was investigated on rat using this method and 125I labeled ATIII. Rat AT III was purified from rat defibrinated plasma by heparin sepharose affinity chromatography and gel filtrations. This purified AT III was used for the preparation of specific AT III antiserum. Labeling of AT III with 125I was performed according to the method by Hunter and Greenwood. Plasma level of AT III were significantly decreased in the treated group with heparin for 6 hours, although significant difference was not observed in AT III contents in various organs. The behavior of i.v. injected AT III laveled with 125I in the normal control and treated groups proved the difference on the half life of AT III. Control group gave 52 hours and it was shortened in the treated group. The percent radioactivity per ml plasma after 6 hours of heparin infusion was 1.16±0.51, and 2.01±0.38 in the control group, and significant difference was observed (p < 0.05). On the contrary the percent dose radioactivity per g tissue wet weight was significantly increased in the liver, lungs, and large intestine on the heparin treated group. The decreased amount of the intravenously injected laveled AT III appears to be trapped and metabolized in the various organs mainly in the liver during heparin infusion. The decrease of plasma AT III levels on the patients treated with heparin may be explained from these experimental results.

Autologous osteochondral transplantation (AOT) is a method for articular cartilage repair. However, several disadvantages of this method have been reported, such as transplanted cartilage degeneration and the lack of a connection between the grafted and adjacent cartilage tissues. To evaluate the effect of intra-articular administration of trichostatin A (TSA) on AOT, we conducted a case control study in a rabbit model. International Cartilage Repair Society (ICRS) macroscopic scores, the modified O’Driscoll histology scores, and real-time PCR were utilized to evaluate the results. At 4 weeks, both macroscopic and histological assessments showed that there was no significant difference between the TSA and control groups. However, the mean macroscopic and histological scores for the TSA-treated group were significantly higher than the scores for the control group at 12 weeks. TSA was shown to directly reduce collagen type II (COL2), aggrecan, matrix metalloproteinase (MMP), and a disintegrin and metalloproteinase domain with thrombospondin motifs 5 (ADAMTS-5) expression and to simultaneously repress the upregulation of MMP-3, MMP-9, and MMP-13 levels induced by interleukin 1β(IL-1β) in chondrocytes. In conclusion, TSA protects AOT grafts from degeneration, which may provide a benefit in the repair of articular cartilage injury.

Abstract Abstract 4226 Patients with childhood ALL achieve long-term disease-free survival, making reducing complications of therapy of major concerns. The aim of this study was to assess the prevalence and degree of neurocognitive dysfunction in survivors of childhood ALL treated with different protocols and the effect of time since end of chemotherapy. Patients and methods: A cross-sectional study including 60 ALL survivors aged 5–16 years at enrollment; 2–9 years at diagnosis, CNS1, treated through 1998–2008 and regularly followed up in childhood cancer survivors clinic;. They were compared to 20 healthy age and sex matched controls. Grade of school, scholastic achievement in the previous year were reported followed by revision of hospital records including type and risk of ALL, protocol of treatment, number, type and dose of intrathecal chemotherapy, number and doses of high dose I.V methotrexate, data of cranial radiotherapy. Three different protocols were applied to these patients according to the time of diagnosis, patients diagnosed between January 1998 to December 2000 were treated with Modified BFM 83. Those diagnosed between January 2001 to June2004 were treated with BFM 90 protocol, and those diagnosed From July 2004 to June 2008 were treated with CCG 1991 for standard risk and CCG 1961 for high risk patients.Neurocognitive functions were tested using Wechsler Intelligence Scale for Children,Benton visual retention (BVR) test and Trail making test (part A and B were done. MRI Brain was performed to the patients and control group using diffusion weighed images and diffusion tensor magnetic resonance imaging (DTI). Results: Survivors treated with CCG protocol showed a significant decrease in all cognitive tests results compared to control (p<0.05). Survivors treated with BFM 90 protocol had a significant lower total IQ, verbal IQ, TMT-partA, compared to both control and survivors treated with Modified BFM 83, and a significant decrease in performance IQ, BVRT and TMT-partB compared to control only. No significant difference between results of cognitive tests in survivors treated with Modified BFM 83 and control group. Both left and right frontal cortex apparent diffusion coefficient (ADC) was significantly higher in CCG(.88±.060.91±.028) treated group compared to control(.695±.0018.684±.0018), BFM 90(.79±.071.76±.048) and modified BFM 83(.76±.030.83±.023×10&minus;3mm2/s) groups (p<0.05) yet a significant decrease in FA of right frontal cortex only in CCG (.250±.039)treated group compared to control(.684±.0018), BFM 90(.450±.042) and Modified BFM 83(.41±.028) groups(p<0.05). FA of right frontal, was significantly lower in BFM 90 and Modified BFM 83 treated group compared to control group. No significant correlation was found between cognitive tests results with age at diagnosis, time since the end of therapy, total number of intrathecal injections, age at radiotherapy treatment, dose and time of radiotherapy. Cognitive tests didn’t differ between survivors treated with triple intrathecal therapy(ITTT) compared to those treated with intrathecal methotrexate, yet significant decrease in FA of right hippocampus in survivors who received ITTT compared to survivors treated with intrathecal monotherapy, Conclusion: Neurocognitive dysfunction was a common sequelae of childhood ALL treatment. It was more related to protocol of therapy rather than the duration of follow-up since end of chemotherapy. Frontal lobe FA may be a clinically useful biomarker for the assessment of neurotoxicity in post-treatment childhood ALL survivors. Disclosures: No relevant conflicts of interest to declare.
