Aerosol chemical composition and distribution during the Pacific Exploratory Mission (PEM) Tropics [PDF]

open access: yes, 1999
Distributions of aerosol-associated soluble ions over much of the South Pacific were determined by sampling from the NASA DC-8 as part of the Pacific Exploratory Mission (PEM) Tropics campaign. The mixing ratios of all ionic species were surprisingly low

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Comparisons of trace constituents from ground stations and the DC-8 aircraft during PEM-West B [PDF]

open access: yes, 1997
Chemical data from ground stations in Asia and the North Pacific are compared with data from the DC-8 aircraft collected during the Pacific Exploratory Measurements in the Western Pacific Ocean (PEM-West B) mission.

Emerging role of ARHGAP29 in melanoma cell phenotype switching

open access: yesMolecular Oncology, EarlyView.
This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

Disparities in opioid treatment access and retention among women based on pregnancy status from 2006 to 2017

open access: yesDrug and Alcohol Dependence Reports, 2022
Background: The purpose of this study is to assess differences in wait time and retention in opioid use disorder (OUD) treatment among a sample of pregnant and non-pregnant women from low-income urban communities in Los Angeles, California. Methods: Data

Influence of vertical transport on free tropospheric aerosols over the central USA in springtime [PDF]

open access: yes, 1998
Measurements of the atmospheric aerosol chemical composition during the Subsonic Aircraft: Contrail and Cloud Effects Special Study (SUCCESS) indicate substantial vertical transport of boundary layer aerosol to the free troposphere over the south-central

Survivin and Aurora Kinase A control cell fate decisions during mitosis

open access: yesMolecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Lead-210 and polonium-210 in the atmosphere [PDF]

open access: yesTellus, 1966
The concentration of Pb-210 has been measured at several altitudes in the atmosphere over the United Kingdom during 1958. The gradient into the lower stratosphere was less steep than observed by Burton & Stewart (1960) and conformed to the diffusion models of Jacobi & Andre (1963) for the case of short washout times, and Machta (1960).

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

open access: yesMolecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Investigating the Relationship Between MiR210 Upregulation and Hemoglobin Gamma Chain Expression [PDF]

open access: yesپیاورد سلامت, 2012
Background and Aim: Micro RNAs are a group of small non-coding RNAs which play an important role in multiple processes such as proliferation, differentiation, apoptosis, and cancer.
