Abstract
BACKGROUND Attentions regarding ordered mesoporous silica materials (OMSs), with large specific surface areas and narrow pore size distribution, which are prepared via self-assembly techniques, have been raised in sorption, separation, and sample preparation. However, in order to extend and improve their applications, a functionalization step is required. Organic units can be anchored on the inner or outer surface as well as in the silica wall framework by co-condensation-, grafting-, and periodic mesoporous organosilica (PMO) preparation approaches. Apparently, by synthesizing PMO with extensive and flexible organic bridging groups within the mesoporous wall, an efficient extractive phase can be achieved. RESULTS We employed tyrosine amino acid to synthesize a PMO-based extractive phase. The FT-IR, 1H NMR, HR-ESI-MS, Low angle-XRD, TEM, FESEM, BET, and EDX-MAP analyses confirmed the successful synthesis of PMO within the salt-assisted templating method. A comprehensive study on sorption behavior of PMO was performed and its efficiency was evaluated against the grafting and co-condensation methods. Then, it was implemented to the pipette tip-micro solid phase extraction (PT-μ-SPE) of widely used non-steroidal anti-inflammatory drugs (NSAIDs) in water/wastewaters. Limits of detection and quantification were obtained in the range of 0.1-1.5 and 0.3-5 μg L-1, respectively. The calibration plots are linear in the 1-1000, 3-1000, 10-750, and 3-750 μg L-1, respectively. The intra-and inter-day precision at 50 and 200 μg L-1 levels are 2.9-7.1 % and 3.5-8%, while recoveries are between 84 and 111 %. SIGNIFICANCE High-capacity tyrosine functionalized PMO with 2D hexagonal symmetry silica mesoporous structures found to be highly efficient extractive media. Despite the bulkiness and flexibility of the bridging group within the mesoporous wall, the synthesis condition was optimized in order to load more organic content in the PMO structure. The PMO performance was superior over organically modified ordered mesoporous silica materials prepared by the grafting and co-condensation methods.

Abstract
Brucellosis is a significant infection that causes abortion, decreased milk production, and sterility in livestock, which greatly affects the industry. This study aimed to determine the prevalence of Brucella in buffalo milk samples across various regions of Iran, utilizing serological, molecular, and cultural analyses. A total of 1860 buffalo milk samples were collected from industrial, semi-industrial, and traditional buffalo farms in four major buffalo breeding provinces. The milk ring test agglutination test (MRT) was initially conducted on all milk samples, followed by culture and molecular testing for positive and negative samples in MRT. The study revealed positive results for the presence of Brucella DNA in various provinces of Iran. The MRT had a relatively low sensitivity, with results ranging from 0 to 0.7% in different provinces. However, the AMOS PCR method showed a significantly higher presence of Brucella DNA, ranging from 13 to 46% in these provinces. The highest abundance of Brucella bacterial DNA was found in Ardabil province, while the lowest was in West Azerbaijan province. Brucella abortus was the most commonly detected bacteria, followed by Brucella melitensis. Interestingly, the B. abortus vaccine strain RB51 was detected in 26.3% of positive samples of B. abortus. The culture assay of milk samples further confirmed the presence of B. melitensis biovar 1 in one sample from Khuzestan province. Overall, the study emphasizes that the AMOS PCR method is the most sensitive in detecting Brucella-exposed milk, while the sensitivity of milk sample culture and MRT is relatively lower.

Abstract
Foot and mouth disease (FMD) is a highly contagious transboundary disease of cloven-hoofed animals. In Iran, the disease is endemic with outbreaks occurring throughout the year. Mass vaccination of domestic ruminants has been adopted as a preventive strategy. A study was conducted to evaluate the effectiveness of currently in use FMD vaccines using official disease surveillance data. Surveillance data of FMD outbreaks and vaccination in cattle farms from January 2017 to March 2019 was obtained from the Iranian Veterinary Organization (IVO). A case-control study comprising 190 laboratory-confirmed cases and 380 randomly selected controls, frequency-matched by location and production type, was performed to estimate vaccine effectiveness (VE) of vaccines in industrial and semi-industrial farms. Multivariable logistic regression was used to estimate odds ratios based on brand of vaccine, time since vaccination, and within-farm vaccination coverage. A total of 2297 outbreaks occurred during the study period with majority (75%) reported from village epi-units. Only 38% of industrial and semi-industrial farms recorded vaccination during the studied period. Vaccination was effective against clinical disease with the highest VE observed in farms vaccinated with commercial vaccine brand A (VE = 0.90%, 95% CI 0.79-0.96), vaccinating > 94% of herd population (VE = 0.77%, 95%CI 0.54-0.98) and in < 35 days after vaccination (VE = 0.56%, 95% CI 0.04-0.8). The current high-potency vaccines confer medium protection in investigated cattle farms. The high occurrence of the disease in village epi-units and low coverage of vaccination in industrial and semi-industrial farms will contribute to maintenance and circulation of the virus in the susceptible population.

Abstract
BACKGROUND Bovine tuberculosis (BTB) is a disease with high economic relevance. AIMS This study aimed to determine a fast alert surveillance system for bTB before the outbreak in the epidemic region of Iran. METHODS This cross-sectional study was conducted using the Auto-Regressive Integrated Moving Average (ARIMA) model for monthly bTB detections (reactors). These reactor cases result from the positive Tuberculin Purified Protein Derivative (PPD) test on cattle farms for the period between April 2007 and March 2019 in Razavi Khorasan province. Autocorrelation functions (ACF) and partial autocorrelation functions (PACF) plots were used to determine model parameters. The Akaike Information Criteria (AIC) were employed to select the best-fitted model. The root mean square error (RMSE) was applied for the evaluation of the models. Then, the best-fitted model was hired to predict the cases for 12 oncoming months. The data were analysed by STATA (ver. 14) software with a significant level at P≤0.05. RESULTS ARIMA (3, 0, 3) 12 was introduced as a recommended fitted model according to white noise residual test (Q=22.87 and P=0.98), lower AIC (541.85), and more precise model RMSE (1.50). However, the forecast values were more than the observed values. CONCLUSION The application and interpretation of ARIMA models are straightforward, and may be used as immediate tools for monitoring systems. However, we proposed an Auto-Regressive Integrated Moving Average with Exogenous Input (ARIMAX) model with some measurable exotic factors such as economic fluctuations, climate changes, and pulmonary tuberculosis to introduce a more precise and accurate model for the fast alert surveillance system.

Abstract
To determine the most prevalent biovar responsible for brucellosis in sheep and goat populations of Iran, a cross-sectional study was carried out over 2 years in six provinces selected based on geography and disease prevalence. Specimens obtained from referred aborted sheep and goat fetuses were cultured on Brucella selective media for microbiological isolation. Brucellae were isolated from 265 fetuses and examined for biovar identification using standard microbiological methods. Results showed that 246 isolates (92.8%) were B. melitensis biovar 1, 18 isolates (6.8%) were B. melitensis biovar 2, and, interestingly, one isolate (0.4%) obtained from Mazandaran province was B. abortus biovar 3. In this study, B. melitensis biovar 3 was isolated in none of the selected provinces, and all isolates from 3 provinces (i.e., Chehar-mahal Bakhtiari, Markazi, and Ilam) were identified only as B. melitensis biovar 1. In conclusion, we found that B. melitensis biovar 1 remains the most prevalent cause of small ruminant brucellosis in various provinces of Iran.

Abstract
The fragile X syndrome, a common X-linked form of mental retardation and autism, affects females as well as males. Previous work has shown that approximately 35% of heterozygotes (women who carry the fragile X gene) demonstrate cognitive impairment. Thirty-two girls, 18 years or younger, who demonstrate the fragile X chromosome were evaluated and compared with 19 sisters who do not demonstrate the fragile X chromosome. Evaluations included a physical examination, behavioral assessment, and intelligence testing. Significant differences (in intellectual, behavioral, and physical features) were seen between the two groups. Twenty-five percent of fragile X-positive girls had an IQ in the mentally retarded range (IQ less than 70) and 28% had an IQ in the borderline range (70 to 84). Prominent ears, shyness, and poor eye contact were significant findings in fragile X-positive girls compared with fragile X-negative girls. Thirty-one percent of the fragile X-positive girls had significant attentional difficulties and most of these girls were successfully treated with stimulant medication. The majority of fragile X-positive girls in this study demonstrated significant behavioral and developmental problems which required identification and appropriate treatment. Pediatricians and health care providers should be aware of the frequency and manner with which fragile X affects females in order to initiate cytogenetic studies and treatment when indicated.

Abstract
Prenatal diagnosis is now available to fragile X (fra[X]) syndrome families and has proven reliable when testing male fetuses. It has been reported that approximately one-third of heterozygous fra(X) females demonstrate mental impairment. Based on this, families usually continue pregnancies involving a female fetus. The purpose of this study is to investigate whether a 35% risk for mental impairment is appropriate when counseling heterozygous women carrying fra(X)-positive female fetuses. Forty-three cytogenetically positive (greater than or equal to 2%) daughters of known fra(X) carrier women were ascertained postnatally in an unbiased fashion. Their mother's carrier status was determined on the basis of at least one son with Martin-Bell syndrome. In addition to peripheral blood cytogenetic studies, all daughters had cognitive testing to determine full-scale IQ. In this study, 55.8% (24/43) were mentally impaired (IQ less than 85) compared with the expected 35%. Of these, 42% were mentally retarded (IQ less than 70). Although we do not know the correlation between percent fragility by peripheral blood compared with the percent fragility by amniocentesis or CVS, we assume that they are relatively comparable such that a female who is positive with greater than or equal to 2% fragility would probably be positive by all methods. This report suggests that the penetrance of mental impairment in females with a percent fragility of greater than or equal to 2% may be as high as 55%. Further studies are necessary to clarify this issue so that accurate information can be given in genetic counseling.

Abstract
A 13-item checklist that combines physical and behavioral traits typical of fragile X [fra(X)] syndrome was evaluated prospectively in the screening of 107 males with mental retardation or severe learning disabilities. The checklist was completed before we obtained cytogenetic results. Fifteen males were fra(X)-positive and the manifestations that differentiated fra(X)-positive and fra(X)-negative patients included perseverative speech, large or prominent ears, large testicles, and tactile defensiveness. The combination of physical and behavioral traits is helpful in suggesting the diagnosis and identifying high-risk patients. A total score of 16 or higher had a significant yield of fra(X)-positive patients (greater than or equal to 45%).

Abstract
Historical, physical, cognitive, and cytogenetic data were documented in 105 heterozygous fragile X [fra(X)] females and 90 controls in a prospective fashion. For comparisons, we divided heterozygotes and controls into those with cognitive impairment (IQ less than 85) and normal IQ (IQ greater than or equal to 85). The only finding that was significantly more frequent in impaired heterozygotes compared with impaired controls chi 2 analysis was shyness. Features that were more frequent in normal IQ heterozygotes compared with normal controls were voluntary thumb dislocation and hyperextensible metacarpal-phalangeal (MP) joints. Comparisons among heterozygotes demonstrated more math problems, hand biting, strabismus, high-arched palate, hyperextensible finger joints, and flat feet in impaired heterozygotes than in normal heterozygotes. Premature menopause was present in 8 of 61 normal heterozygotes and in none of the impaired heterozygotes. A multiple regression analysis demonstrated a significant inverse correlation between the percent fragility and IQ for the heterozygotes as a group. However, no correlation existed between IQ and fragility when the percent fragility was 2% or greater. However, a higher percentage of fragility was positively correlated with the total number of physical findings present.
