Sexual behavior is a routine among animal species. Sexual experience has several behavioral consequences in insects, but its physiological basis is less well-understood. The episodic motor activity with a periodicity around 19 s was unintentionally observed in the wildtype Canton-S flies and was greatly reduced in the white-eyed mutant w1118 flies. Episodic motor activity co-exists with several consistent locomotor performances in Canton-S flies whereas reduced episodic motor activity is accompanied by neural or behavioral abnormalities in w1118 flies. The improvements of both episodic motor activity and locomotor performance are co-inducible by a pulsed light illumination in w1118. Here we show that mating experience of w1118 males promoted fast and consistent locomotor activities and increased the power of episodic motor activities. Compared with virgin males, mated ones showed significant increases of boundary preference, travel distance over 60 s, and increased path increments per 0.2 s. In contrast, mated males of Canton-S showed decreased boundary preference, increased travel distance over 60 s, and increased path increments per 0.2 s. Additionally, mated males of w1118 displayed increased power amplitude of periodic motor activities at 0.03-0.1 Hz. find more These data indicated that mating experience promoted fast and consistent locomotion and improved episodic motor activities in w1118 male flies.Nanoparticles possess unique, size-driven properties. However, they can be challenging to use as they easily agglomerate - their high surface area-to-volume ratio induces strong interparticle forces, generating agglomerates that are difficult to break. This issue prevails in organic particles as well, such as cellulose nanocrystals (CNCs); when in their dried form, strong hydrogen bonding enhances agglomeration. Ultrasonication is widely applied to prepare CNC suspensions, but the methodology employed is non-standardized and typically under-reported, and process efficiency is unknown. This limits the ability to adapt dispersion protocols at industrial scales. Herein, numerical simulations are used in conjunction with validation experiments to define and optimize key parameters for ultrasonic dispersion of CNCs, allowing an operating window to be inferred.

Central nervous system (CNS) metastases are common complications in epidermal growth factor receptor (EGFR) mutant non-small-cell lung cancer (NSCLC) treated with EGFR-tyrosine kinase inhibitors (TKIs). However, for patients without baseline CNS metastasis, data regarding the incidence of symptomatic CNS metastasis with EGFR-TKI treatment and its risk factors are still rare.

Patients with EGFR-mutant advanced NSCLC without baseline CNS metastasis who are receiving first- and/or third-generation EGFR-TKIs were included. Overall survival (OS), cumulative incidence of symptomatic CNS metastasis upon treatment failure, and their risk factors were evaluated.

There were 813 patients enrolled, with 562, 106, and 32 received first-line gefitinib, erlotinib, and osimertinib, respectively, while 113 received second-line osimertinib. At a median follow-up of 18.1 months, the median OS was 45.5 months. There were 38 patients developed symptomatic CNS metastases. Osimertinib-treated patients tended to have a lower risk of CNS metastases compared with those treated with first-generation EGFR-TKIs (p = 0.059). However, the cumulative incidence curves of symptomatic CNS metastasis tended to reach a plateau after approximately 3 years regardless of which generation was used, and incidences beyond that period were similar in the two groups. Patients with L858R mutation exhibited a higher risk of developing CNS metastasis than patients with 19del mutation (p = 0.001). Interestingly, the presence of baseline neuroimaging was not associated with the risk of developing CNS metastasis or OS.

Compared with first-generation EGFR-TKIs, osimertinib can delay but not prevent the development of symptomatic CNS metastasis. L858R mutation is an independent risk factor for CNS metastasis.

In recent years immunotherapy has escalated to frontline treatment options for metastatic non-small cell lung cancer. Cardiovascular toxicity from chemotherapeutic agents is well described in this patient population with common underlying risk factors like smoking. We explored cardiovascular toxicity form the addition of immune checkpoint inhibitors to traditional chemotherapy.

This is a retrospective study from SEER-Medicare datasets which represents 34 % of the US population. This study included patients age ≥ 65 years-old with newly diagnosed metastatic non-small cell lung cancer between the years 2013 and 2015. Patients were divided into 2 cohorts, one who received traditional chemotherapy only (control arm) and the others who received immune checkpoint inhibitors in addition to traditional chemotherapy (study arm). The primary endpoint was the hazards of new cardiovascular toxicity in the study versus the control arm.

We identified 6405 patients who met our study criteria. Of these, 5730 patients rwer hazards.

Results from this study are reassuring that adding immune checkpoint inhibitors to chemotherapy is safe and does not result in increased cardiovascular toxicity but instead showed lower hazards.

Health-related quality of life (HRQoL) data complement conventional clinical endpoints when comparing adjuvant gefitinib with chemotherapy in patients with early-stage non-small-cell lung cancer (NSCLC) and epidermal growth factor receptor (EGFR) mutations. This study aimed to assess changes in HRQoL with adjuvant gefitinib vs chemotherapy in this patient group.

In the phase III ADJUVANT trial, patients with completely resected, stage II-IIIA (N1-N2), EGFR-mutant NSCLC were randomized (11) to receive either gefitinib for 24 months or vinorelbine plus cisplatin (VP) every 3 weeks for four cycles. HRQoL was assessed as a secondary endpoint using the Functional Assessment of Cancer Therapy-Lung Cancer (FACT-L), Lung Cancer Symptom Scale (LCSS) questionnaires, and Trial Outcome Index (TOI) composite score. HRQoL dynamics, improvements, and time to deterioration were compared between groups.

At baseline, 104 of 106, and 80 of 87 patients receiving gefitinib and VP, respectively, completed two questionnaires (FACT-L and LCSS).
