Background: Dopamine transporter (I-FP-CIT) single-photon emission tomography (SPECT) and I-meta-iodobenzylguanidine (I-MIBG) image play roles as indicative biomarkers in diagnosing patients with dementia with Lewy bodies (DLB). Brain- and body-first subtypes of DLB were hypothesized implying that subset of DLB may have normal I-FP-CIT or I-MIBG results, respectively. The purpose of this study was to explore the diagnostic sensitivity of two combination imaging modalities (I-FP-CIT SPECT and I-MIBG image) in patients with DLB and examine the clinical difference between brain- and body-first subtype.

Article Synopsis
  • Balloon-assisted enteroscopy (BAE) is an invasive procedure with risks like pain and perforation, but using lubricants can help reduce these risks.
  • A study developed a model using human small intestines to measure dynamic friction coefficients (DFC) and find the ideal viscosities for low-friction lubricants.
  • The results indicate that the viscosity of lubricants (0.20-0.32 Pa·s for overtube and 0.35-0.58 Pa·s for endoscopic shaft) significantly reduces DFC, suggesting that appropriate lubricants can make BAE less invasive.

To achieve the desired delivery effect, extracellular vesicles (EVs) must bypass rapid clearance from circulation and exhibit affinity for target cells; however, it is difficult to simultaneously incorporate two materials into EVs. Post-insertion is a general modification method that can be performed by simply mixing different solutions. Previously, we have developed a microfluidic post-insertion method that supported fast and upscaled modification of EVs using KK-modified high-functionality and -quality (HFQ) lipids.

  • The JCOG0306 trial studied the effectiveness of neoadjuvant chemotherapy followed by radiation therapy in primary breast cancer, comparing the representative specimen (RS) method to the traditional total specimen (TS) method for evaluating pathological complete response (pCR).
  • The study involved 103 patients, assessing pCR and quasi-pCR rates with both methods, and found that RS had a higher concordance rate with better identification of strong prognostic groups.
  • Results indicated that both RS and TS methods provided similar prognostic outcomes for pCR groups, but RS method had significant advantages in differentiating patient survival rates more effectively than TS.

Background: Dementia with Lewy bodies (DLB) presents with various symptoms, posing challenges for early diagnosis challenging. Dopamine transporter (123I-FP-CIT) single-photon emission tomography (SPECT) and 123I-meta-iodobenzylguanidine (123I-MIBG) imaging are crucial diagnostic biomarkers. Hypothesis about body- and brain-first subtypes of DLB indicate that some DLB may show normal 123I-FP-CIT or 123I-MIBG results; but the characteristic expression of these two subtypes remains unclear.

To clarify the regulation of drug absorption by the enteric nervous system, we investigated how adrenergic agonists (adrenaline (ADR), clonidine (CLO), dobutamine (DOB)) and dibutyryl cAMP (DBcAMP) affected P-glycoprotein (P-gp) function by utilizing isolated rat jejunal sheets and Caco-2 cell monolayers. ADR and CLO significantly decreased the secretory transport (P) of rhodamine-123 and tended to decrease the transport via P-gp (P) and passive transport (P). In contrast, DBcAMP significantly increased and DOB tended to increase P and both tended to increase Pand P.

Accurate quantification of infectious contaminants on environmental surfaces, particularly infectious viruses, is essential for contact transmission risk assessment; however, difficulties in recovering viruses from surfaces using swabs complicates this quantification process. Herein, we identified the factors that significantly affected virus recovery rates and developed an ideal swab method that yielded the highest rate of virus recovery. We comprehensively analyzed the effects of swab type (cotton/polyester), swab water content (wet/dry conditions), surface material, and surface area on the rates of viral RNA and infectious virus recovery.
