Abstract
Bone healing is still a great challenge in orthopedic surgery and clinical practice. There is a dearth of research investigating the effect of Zeolite/Collagen (ZC) nanocomposite on bone regeneration. In the present study, a critical segmental defect of the rabbit femur was repaired using defects in femurs repaired by ZC nanocomposite, and the effects were examined histologically. In total, 45 rabbits at seven months of age weighing 3.5 kilograms were utilized in this study. After making the bone defects, all animals were randomized into three groups (n=15). In a normal control group (NC), a defect was created, no intervention was made, and the skin incision was sutured. On the other hand, in the ZC group, the nanocomposite of ZC was placed into the created defect. In the hydroxyapatite group (HA), the hydroxyapatite was placed into the created defect. The samples were collected on days 15, 30, and 45 postoperatively and assessed histopathologically. The mean scores of the index of the union were compared and considerable alterations were observed in this regard in the experimental groups (P<0.05). The values of the index of spongiosa demonstrated that on day 15, it was the highest in the ZC group (2.2) and lowest in the HA and NC groups (0.6). Moreover, the values of the index of bone marrow demonstrated no noticeable alteration among the values of the index of bone marrow in the experimental groups (P>0.05). The findings of this study demonstrated that ZC nanocomposite might be considered for reconstruction in bone damages. It seems the ZC nanocomposite bears a crucial capability in the reconstruction of bone damages and might be used as a biological frame in bone damages.

Abstract
Anesthesia and analgesia are important in human and veterinary medicine, especially in surgical procedures. Rodents, avians, and exotic species are required to be anesthetized using an appropriate anesthetic regimen. This study aimed to suggest a new anesthetic drug and method in order to facilitate anesthesia as well as analgesia among rabbits, laboratory animals, and humans. Spinal injection of dexamethasone combined with intramuscular ketamine among rabbits can play the role of premedication agents. A total of 24 healthy white adult rabbits from New-Zealand were equally assigned into four groups. Groups 1, 2, 3, and 4 were subjected to spinal xylazine (5mg/kg) with ketamine (35mg/kg,IM), spinal dexamethasone (0.37mg/kg-four times diluted) with ketamine (35mg/kg,IM), dexamethasone (4mg/kg,IM) with ketamine (35mg/kg,IM), and spinal dexamethasone (0.37mg/kg-four times diluted), respectively. The results showed that there was a significant difference in terms of clinical reflexes recorded for group 2, compared to groups 1 and 3. A significant difference was also observed regarding clinical reflexes between group 2 and the other groups. Furthermore, no abnormality was observed in terms of histological sections within groups 2 and 4. Spinal dexamethasone can be used as a premedication combined with ketamine in rabbit anesthesia.

Abstract
In this research, a magnetic graphitic carbon nitride (g-C3N4-SnFe2O4) was successfully synthesized and utilized as an efficient adsorbent for nickel (Ni2+) separation/extraction from vegetable samples by ultrasound-assisted magnetic dispersive micro solid-phase extraction (UA-M-D-μSPE). After separation and preconcentration step, Ni ions were determined via micro-sampling flame atomic absorption spectrometry (MS-FAAS). A successful synthesis of g-C3N4-SnFe2O4 was investigated by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and vibrating sample magnetometer (VSM). The optimization of adsorption and desorption steps was effectively studied by the on-at-a time method. In addition, under the optimum experimental conditions, the limits of detection (LODs), the linear ranges (LR) and relative standard deviations (RSDs%, for n = 5) were obtained 1.0 μg.L−1, 4.0 ─ 500.0 μg.L−1, and 1.4 respectively.

Abstract
The activities of cobalt catalysts prepared by the microemulsion impregnation method on carbon nanotubes (CNTs) and functionalised carbon nanotubes (FCNTs) supports were evaluated in the Fischer–Tropsch synthesis (FTS). The catalysts were characterised by transmission electron microscopy, X-ray diffraction and Brunauer–Emmett–Teller surface area methods. The results show that the cobalt particles in the FCNTs support are mostly located inside the tubes of the CNTs and show a narrower particle size distribution. The experimental results show that the cobalt catalyst supported on FCNTs leads to a higher CO conversion and FTS activity compared to that supported on normal CNTs. Calculated kinetic results show that the activation energies fall within the narrow range of 101.1–107.1 kJ mol−1 and the heat of hydrogen adsorption was calculated to be −40.2 and −26.2 kJ mol−1 for Co/CNTs and Co/FCNTs catalysts respectively. FCNTs, as a catalyst support of Co nanoparticles, maintain high dispersion which can be attributed to a hydrogen spillover effect of functional groups on the CNT surface.

Abstract
The present study was conducted with the aim of comparing the effects of premedication with ketoprofen and midazolam in birds. A total of 24 male pigeons with an approximate weight of 300 g were divided into four equal groups. The control group (Group I) was injected with ketamine alone. Groups II-IV were injected with ketoprofen alone, ketoprofen+ketamine, and midazolam+ketamine, respectively. The biochemical changes in the four groups were evaluated after intramuscular drug injections at different anesthetic levels. A record of biochemical changes was maintained for each group. Blood samples were taken before and after the administration of the medications in order to measure the levels of serum alkaline phosphatase (ALP), oxaloacetate transaminase (OT), prothrombin time (PT), glucose (GLU), lactate dehydrogenase (LDH), albumin (Alb), total protein (TP), and gamma-glutamyl transferase (GGTF). The results showed significant differences in the mean levels of ALP, OT, PT, GLU, LDH, Alb, and TP after anesthesia, compared to that before anesthesia. Therefore, ketoprofen+ketamine can be used for the induction of anesthesia in birds.The present study was conducted with the aim of comparing the effects of premedication with ketoprofen and midazolam in birds.

Abstract
In this work, a rapid and efficient procedure named ultrasound meliorated dispersive micro solid-phase extraction followed by high performance liquid chromatography-ultra violet detection (US-D-μSPE-HPLC-UV) was developed for the pre-concentration of the main trace anti-hypertensive drugs in complex matrices. The basis of this procedure was a polypyrrole-sodium dodecylbenzenesulfonate/zinc oxide (PPy-DBSNa/ZnO) nanocomposite. It was readily synthesized by the impressive way of in situ sonochemical oxidative polymerization in the presence of some additives such as FeCl3 and DBSNa, ultimately leading to the effective coating of PPy on the ZnO nanoparticle cores. Characterization of the proposed nanosorbent was performed by different techniques such as FESEM, XRD,EDX, and TGA, confirming the high quality and proper physico-chemical properties of the proposed sorbent. In order to better investigate the input variables, the central composite design (CCD) combined with the desirability function (DF) was utilized. The enriched optimum conditions consisted of the initial pH value of 11.8, 15mg of the PPy-DBSNa/ZnO nanocomposite, a sonication time of 4.6min, and 100μL of methanol, resulting in maximum responses at a relatively low extraction time with a logical DF. Under the optimum conditions, good linearity (5-5000, 2.5-3500, and 2.5-3000ngmL-1 for metoprolol, propranolol, and carvedilol, respectively, with the correlation of determinations (R2s) higher than 0.99), low limits of detection (LODs) (0.8-1.5ngmL-1), proper repeatabilities (relative standard deviation values (RSDs) below 6.3%, n=3), reasonable enrichment factors (EFs) (60-72), and good extraction recoveries (ERs) (higher than %75) were obtainable. These appropriate validations corroborated a good effectiveness of ultrasonic waves in the achievement of a supreme solid phase as well as a facile and efficient microextraction of the low therapeutic concentrations in human plasma and urine samples.
