Purpose: This work was conducted to describe the formant frequencies in a group of Middle Eastern singers and to look for the presence of the singer's formant described in operatic singers.
Material: A total of 13 Middle Eastern singers were enrolled in this study. There were 5 men and 8 women.
Method: Descriptive analysis was performed to report the various formants (F1, F2, F3, and F4) in both speaking and singing. The Wilcoxon test was used to compare the means of the formants under both conditions.
Results: For both sexes combined, for the /a/ vowel, F1 singing was significantly lower than F1 speaking (P = .05) and F3 singing was significantly higher than F3 speaking (P = .046). For the /u/ vowel, only F2 singing was significantly higher than F2 speaking (P = .012). For the /i/ vowel, both F2 and F3 singing were significantly lower than F2 and F3 speaking, respectively (P = .006 and .012, respectively). There was no clustering of the formants in any of the Middle Eastern sung vowels.
Conclusion: Formant frequencies for the vowels /a/, /i/, and /u/ differ between Middle Eastern singing vs speaking. There is absence of the singer's formant.

Using rare cancer predisposition alleles derived from The Cancer Genome Atlas (TCGA) and high cancer prevalence (14% of participants) in All of Us (version 6), we assessed the impact of these rare alleles on cancer occurrence in six broad groups of genetic similarity provided by All of Us: African/African American (AFR), Admixed American/Latino (AMR), East Asian (EAS), European (EUR), Middle Eastern (MID), or South Asian (SAS). We observed that germline susceptibility to cancer consistently replicates in EUR-like participants but less so in other participants. We found that All of Us participants from the EUR (p = 1.

Background: There is a paucity of data on oral health problems among the residents of Fanteakwa districts (South and North) in the Eastern region of Ghana. Therefore, this study assessed the prevalence and factors associated with self-reported oral health problems in the Fanteakwa districts of Ghana.
Methods: This community-based cross-sectional study targeted residents of the towns of the Fanteakwa districts, who have not had any dental care visit in the past six months preceding the study.
The Impacts of Programs and Policies to Address Food Insecurity: An Analysis of Change in Income.

Department of Community Health Sciences, Boston University School of Public Health, 801 Massachusetts Ave. 4th Floor, Boston, MA 02118, USA.
Background/objectives: This paper examines hunger over time to analyze how food insecurity is impacted by reduced income, including household funding from the government. Federal policies and community-based programs have the ability to prevent increases in food insecurity, particularly for populations that have risk factors, such as households with children; single-parent households; low-income households, especially those in rural areas; Black and Hispanic households; and, households experiencing economic hardships.
Methods: This study is bas ed on a cross-sectional survey that was administered in 2018 and 2019 to food pantry clients, an already food insecure population accessing resources, in Eastern Massachusetts.

Background: The human gut microbiota develops in concordance with its host over a lifetime, resulting in age-related shifts in community structure and metabolic function. Little is known about whether these changes impact the community's response to microbiome-targeted therapeutics. Providing critical information on this subject, faecal microbiomes of subjects from six age groups, spanning from infancy to 70-year-old adults (n = six per age group) were harvested.

The process of regional economic development is marked by a sustained exposure to external disturbances. In today's unpredictable and tumultuous global environment, such disturbances have become increasingly common, underlining the need to advance a region's economic resilience and foster adaptive mechanisms to handle environmental flux. Comparing the typical provinces in eastern, central, western and northeastern regions during the COVID-19 epidemic period, it found that the economic resilience performance of Henan Province, which is a representative of the central region, has the following characteristics.
