Invasion of the stigma by oomycete pathogenic hyphae or pollen tubes: striking similarities and differences.

Both the pollen tube and hyphae of filamentous pathogens penetrate the outer layer of the host and then grow within host tissues. Early epidermal responses are decisive for the outcome of these two-cell interaction processes. We identified a single cell type, the papilla in the stigma of Arabidospis, as a tool to conduct a comprehensive comparative analysis on how an epidermal cell responds to the invasion of an unwanted pathogen or a welcome pollen tube.

Comorbid psychiatric conditions with temporomandibular disorders (TMD) in a tertiary referral clinic.

Patients with chronic pain have a higher prevalence of mood disorders with depression and anxiety contributing to higher pain intensity, emotional allodynia, and neuro-anatomical changes. We sought to quantify the prevalence of psychiatric comorbidities (PCs) in a tertiary referral clinic for temporomandibular disorders (TMDs). Medical records of all patients attending clinics run by three tertiary temporomandibular joint (TMJ) surgeons for the period January to April 2022 inclusive were audited for the prevalence of concomitant psychiatric conditions.

Automated high-content image-based characterization of microorganism behavioral diversity and distribution.

Microorganisms have evolved complex systems to respond to environmental signals. Gradients of particular molecules and elemental ions alter the behavior of microbes and their distribution within their environment. Microdevices coupled with automated image-based methods are now employed to analyze the instantaneous distribution and motion behaviors of microbial species in controlled environments at small temporal scales, mimicking, to some extent, macro conditions.

Management of Psychiatric Conditions in Patients With Comorbid Postural Orthostatic Tachycardia Syndrome: A Literature Review and Case Vignette.

Disorders of the autonomic nervous system are relatively common and have a significant impact on quality of life, offer very subtle diagnostic clues, and often mimic other disease processes, including certain psychiatric disorders. Pharmacologic treatment for psychiatric conditions in this group of patients can also be complicated by the pathophysiology of the various syndromes. Postural orthostatic tachycardia syndrome (POTS) is the final common pathway of a heterogenous group of underlying disorders that display similar characteristics.
