Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Reproductive protein protects functionally sterile honey bee workers from oxidative stress [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Research on aging shows that regulatory pathways of fertility and senescence are closely interlinked. However, evolutionary theories on social species propose that lifelong care for offspring can shape the course of senescence beyond the restricted context of reproductive capability. These observations suggest that control circuits

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Anthropological Differences between Contraception and Natural Family Planning [PDF]

open access: yes, 2000
Almost twenty years ago, Pope John Paul II in his apostolic exhortation Familiaris Consortio called on scholars to study the anthropological and moral differences between the recourse to the natural rhythms of a woman’s menstrual cycle (i.e., natural ...

Hybrid male sterility and genome-wide misexpression of male reproductive proteases [PDF]

open access: yesScientific Reports, 2015
AbstractHybrid male sterility is a common barrier to gene flow between species. Previous studies have posited a link between misregulation of spermatogenesis genes in interspecies hybrids and sterility. However, in the absence of fully fertile control hybrids, it is impossible to differentiate between misregulation associated with sterility vs.

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

An Analysis of the Majority Report “Responsible Parenthood” and its Recommendations on Abortion, Sterilization and Contraception [PDF]

open access: yes, 2003
This paper will focus on the majority report (titled “Responsible Parenthood”) of the 1966 Papal Birth Control Commission and its recommendations on abortion, sterilization, and contraception.(1) The analysis is made with the hindsight and perspective of

China\u27s Population Policy In Historical Context [PDF]

open access: yes, 2016
The year 2014 marked the de facto end to China’s “one-child policy,” the most extreme example of state intrusion into the realm of reproduction. Deng Xiaoping’s 1979 initiative built on earlier, short-lived “birth planning” campaigns. The 1979 policy set

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,
