, the sugar beet root maggot (SBRM), is a devastating insect pathogen of sugar beet, one of only two plants in the world from which sugar is widely produced, accounting for 55% of U.S. sugar and 35% of global raw sugar with an annual farm value of $3 billion in the United States.

Pathogen-secreted polygalacturonases (PGs) alter plant cell wall structure by cleaving the α-(1 → 4) linkages between D-galacturonic acid residues in homogalacturonan (HG), macerating the cell wall, facilitating infection. Plant PG inhibiting proteins (PGIPs) disengage pathogen PGs, impairing infection. The soybean cyst nematode, Heterodera glycines, obligate root parasite produces secretions, generating a multinucleate nurse cell called a syncytium, a byproduct of the merged cytoplasm of 200-250 root cells, occurring through cell wall maceration.

The plant cell wall structure can be altered by pathogen-secreted polygalacturonases (PGs) that cleave the α-(1→4) linkages occurring between D-galacturonic acid residues in homogalacturonan. The activity of the PGs leads to cell wall maceration, facilitating infection. Plant PG inhibiting proteins (PGIPs) impede pathogen PGs, impairing infection and leading to the ability of the plant to resist infection.

This study examined differences in colorectal cancer screening across sociodemographic, migration, occupational, and health-related factors in a sample of male taxi drivers. Male drivers eligible for colorectal cancer screening (CRCS) (≥ 50 years old) were recruited in 55 community-based health fairs conducted during November 2015 to February 2017 in 16 taxi garages or community locations located in Queens, Brooklyn, Manhattan and Bronx. Participants completed a survey that included sociodemographic, migration, occupational, health-related, and cancer screening practices.

Exposure to fine particulate matter (PM) and black carbon (BC) have been linked to negative health risks, but exposure among professional taxi drivers is understudied. This pilot study measured drivers' knowledge, attitudes, and beliefs (KAB) about air pollution compared with direct measures of exposures. Roadside and in-vehicle levels of PM and BC were continuously measured over a single shift on each subject, and exposures compared with central site monitoring.

Gutka and tambaku paan (smokeless tobacco products used by South Asian immigrants) are carcinogenic to humans (and perceived as such), yet, one-fourth of South Asian immigrants report current use. This study examined disengagement beliefs that perpetuate gutka/tambaku paan use among South Asians despite awareness of health risks. Six focus groups were conducted with immigrant South Asian adult gutka/tambaku paan users, in Gujarati, Bengali and Urdu languages in New York, USA.

Smokeless tobacco use is prevalent among South Asian immigrants, particularly in the forms of gutka and tambaku paan. In this paper, we examined (a) gutka and tambaku paan initiation and use patterns among South Asian immigrants, and (b) perceptions related to quitting and tobacco control. Six focus groups were conducted with 39 South Asian adult gutka/tambaku paan users, in three different South Asian languages (Gujarati, Bengali, and Urdu).

South Asian (SA) taxi drivers potentially possess a double epidemiologic risk for cardiovascular disease (CVD) due to their ethnicity and occupation. This study investigates SA taxi drivers' knowledge, attitudes, beliefs about general health, CVD and approaches to reduce CVD risk. Five focus groups were conducted with 31 SA taxi drivers in the participants' primary language (Bengali, Hindi, Urdu or Punjabi).

Research involving general patients suggests that most patients agree to be involved in medical education but prefer not to discuss personal or stress related issues with/in front of medical students. We explore the opinions and experiences of mentally ill in-patients of their involvement in undergraduate medical education in psychiatry. The study shows that patients attach importance to students seeing real patients and that the patients are happy to be seen by medical students.
