Studies of charmonium-like states at BABAR
Several charmonium-like states above threshold have been
discovered at the Belle and BABAR B-factories. Some of these states are
produced via Initial State Radiation (e.g. Y(4260) and Y(4350)), and some are
observed in B-meson decays (e.g. X(3872), and Y(3940)). The Belle observations
of the enhancements in the and , i.e. the
Z(4430)-, Z_1(4050)-, and Z_2(4250)-, have generated a great deal of interest,
because such states must have minimum quark content , i.e.
these are candidate four-quark state. The BABAR Collaboration does not confirm

Search for a low-mass Higgs boson () at BABAR
The BABAR Collaboration has performed three searches for a light Higgs boson,
, in radiative Upsilon () decays: ,

(); and , invisible. Such a Higgs
boson () appears in the Next-to-Minimal Supersymmetric extensions of the
Standard Model, where a light CP-odd Higgs boson couples strongly to
-quarks. The searches are based on data samples that consist of and decays, collected by
the BABAR detector at the SLAC National Accelerator Laboratory. The searches
reveal no evidence for an , and product of branching fractions upper

THE ASSOCIATION OF TYPE 2 DIABETES WITH OBESITY AND OTHER FACTORS: IN MULTINATIONAL COMMUNITY
Objective: Quantifying the influence of Obesity and other contributing factors on inducing Type 2 Diabetes is important to allow for rational planning and allocation of resources. Therefore, the major aim of this study was to estimate theinfluence of obesity on inducing Type 2 Diabetes and explore the relationship between Type 2 Diabetes and different contributing factors such as age, gender, race, type of food taken and family history in a many healthy and non-healthy human multinational volunteers in the United Arab Emirates.
Methods: A stratified cross-sectional analysis observational study was conducted on 800 healthy males and non-pregnant female volunteers aged between 18 and 45 years old. A Structured Investigational Assessment (SIA) as a principle of analysis was used to find out the contributing factors and correlations between obesity and Type 2 Diabetes. SIA was well designed and highly structured to allow the same types of information to be collected from a large number of people in the same way and for data to be analyzed quantitatively and systematically. Information obtained from volunteers contained age, race, gender, weight, height, quality of food taken, smoking status, medical conditions, emotional, material and physical activity status. Pearson's chi square test was used to study the significance of different contributing factors and obesity on inducing Type 2 Diabetes.
Results: Results indicated a significant difference that was found between the presences of Type 2 Diabetes in obese volunteers compared to non-obese volunteers regardless, age, race, and gender. However, analysis showed that gender, age, race, family history with Type 2 Diabetes and quality of food taken as one of the contributed factors that can induce Type 2 Diabetes, even in the non-obese adults.
Conclusion: Our findings revealed that female, Middle Eastern and obese people who consume non-healthy food are at higher risk for developing Type 2 Diabetes. This can be attributed to the lack of awareness and public health education. Therefore,the prevalence of Type 2 Diabetes is high among the United Arab Emirates population and represents a major clinical and public health problem. A national prevention program to prevent diabetes and address the modifiable risk factors at the community level, targeting high-risk groups, should be implemented
