“That means nothing to me as a normal person who doesn\u27t know about patents”: Usability testing of Google Patents and Patent Public Search with undergraduate engineering students
Patent searching is an important research tool for undergraduate engineering students, yet it requires special topic knowledge to conduct successfully. Patent database websites have the ability to alleviate or add to the complexity of patent searching, depending on their usability. Prompted by the launch of the US Patent and Trademark Office’s Patent Public Search (PPS) website in early 2022, the authors investigated the usability of PPS and Google Patents. The study\u27s objective was to gain insights into the ways in which the websites of commonly-used patent databases support undergraduate students’ patent searching activities. The study examined students’ performance of typical tasks such as constructing search queries, filtering results, evaluating results, and interpreting classification and citation data. Data was collected via moderated in-person usability testing, following a think-aloud protocol. Usability issues were identified in both websites, though participants unanimously preferred Google Patents due to their familiarity with other Google products and the “cleaner” design of the search interface. Based on the study’s results, the authors offer recommendations for patent literacy instruction for undergraduate students

PETALS: AN ASSESSMENT OF THE OUTCOMES OF A SERVICE FOR BEREAVEMENT DURING CHILDBIRTH
Objectives: We aimed to evaluate the outcomes of Petals: a charitable organisation in Cambridgeshire. Petals provides
counselling for women and couples who have suffered perinatal bereavement, or trauma during pregnancy or birth. This paper
attempts to evaluate the effect of counseling interventions at this difficult time.
Methods: Outcomes were recorded in 42 patients using the CORE (Clinical Outcomes in Routine Evaluation) system. CORE was
developed to assess the effectiveness of psychological therapies. CORE-OM (CORE Outcome Measure) involves a questionnaire that
assesses subjective well-being, symptoms / problems, function, and risk to self and others. The CORE-OM questionnaire was
completed before and after the counselling sessions.
Results: The CORE-OM scores were summated into a global representation of severity. Severity decreased in all patients.
Symptoms of psychological pathology were also decreased in all cases.
Conclusion: A review of the available literature indicates that little is known about the efficacy of therapy for perinatal
bereavement and trauma. These original data suggest convincing efficacy and benefits, but the numbers involved are small.Further
trials with greater sample sizes are required
EVALUATION OF A SPECIALISED COUNSELLING SERVICE FOR PERINATAL BEREAVEMENT
Objectives: We aimed to evaluate the outcomes of Petals: a charitable organisation in Cambridgeshire. Petals provides
counselling for women and couples who have suffered perinatal bereavement, or trauma during pregnancy or birth. This paper
attempts to evaluate the effect of counseling interventions at this difficult time.
Methods: Outcomes were recorded in 107 patients using the CORE (Clinical Outcomes in Routine Evaluation) system. CORE
was developed to assess the effectiveness of psychological therapies. CORE-OM (CORE Outcome Measure) involves a questionnaire
that assesses subjective well-being, symptoms/problems, function, and risk to self and others. The CORE-OM questionnaire was
completed before and after the counselling sessions.
Results: The CORE-OM scores were summated into a global representation of severity. Severity decreased in all patients.
Symptoms of psychological pathology were also decreased in all cases.
Conclusion: Offering a free specialised counselling for parents suffering perinatal loss seems to be associated with an
improvement in psychological outcomes. It is possible that it is more effective among a clinical population. However, we are
uncertain of the natural history of the psychological problems this group of clients are experiencing. Having a control group would
show how much of any natural improvement is due to the therapy; conversely, it is possible that without intervention these problems
worsen with time, so a control group could actually amplify the effect
Functional Association Between Three Archaeal Aminoacyl-tRNA Synthetases
Aminoacyl-tRNA synthetases (aaRSs) are responsible for attaching amino acids to their cognate tRNAs during protein synthesis. In eukaryotes aaRSs are commonly found in multi-enzyme complexes, although the role of these complexes is still not completely clear. Associations between aaRSs have also been reported in archaea, including a complex between prolyl-(ProRS) and leucyl-tRNA synthetases (LeuRS) in Methanothermobacter thermautotrophicus that enhances tRNAPro aminoacylation. Yeast two-hybrid screens suggested that lysyl-tRNA synthetase (LysRS) also associates with LeuRS in M. thermautotrophicus. Co-purification experiments confirmed that LeuRS, LysRS, and ProRS associate in cell-free extracts. LeuRS bound LysRS and ProRS with a comparable KD of about 0.3–0.9 μm, further supporting the formation of a stable multi-synthetase complex. The steady-state kinetics of aminoacylation by LysRS indicated that LeuRS specifically reduced the Km for tRNALys over 3-fold, with no additional change seen upon the addition of ProRS. No significant changes in aminoacylation by LeuRS or ProRS were observed upon the addition of LysRS. These findings, together with earlier data, indicate the existence of a functional complex of three aminoacyl-tRNA synthetases in archaea in which LeuRS improves the catalytic efficiency of tRNA aminoacylation by both LysRS and ProRS
Characterization of wild and captive baboon gut microbiota and their antibiotic resistomes
Antibiotic exposure results in acute and persistent shifts in the composition and function of microbial communities associated with vertebrate hosts. However, little is known about the state of these communities in the era before the widespread introduction of antibiotics into clinical and agricultural practice. We characterized the fecal microbiota and antibiotic resistomes of wild and captive baboon populations to understand the effect of human exposure and to understand how the primate microbiota may have been altered during the antibiotic era. We used culture-independent and bioinformatics methods to identify functional resistance genes in the guts of wild and captive baboons and show that exposure to humans is associated with changes in microbiota composition and resistome expansion compared to wild baboon groups. Our results suggest that captivity and lifestyle changes associated with human contact can lead to marked changes in the ecology of primate gut communities.Environmental microbes have harbored the capacity for antibiotic production for millions of years, spanning the evolution of humans and other vertebrates. However, the industrial-scale use of antibiotics in clinical and agricultural practice over the past century has led to a substantial increase in exposure of these agents to human and environmental microbiota. This perturbation is predicted to alter the ecology of microbial communities and to promote the evolution and transfer of antibiotic resistance (AR) genes. We studied wild and captive baboon populations to understand the effects of exposure to humans and human activities (e.g., antibiotic therapy) on the composition of the primate fecal microbiota and the antibiotic-resistant genes that it collectively harbors (the “resistome”). Using a culture-independent metagenomic approach, we identified functional antibiotic resistance genes in the gut microbiota of wild and captive baboon groups and saw marked variation in microbiota architecture and resistomes across habitats and lifeways. Our results support the view that antibiotic resistance is an ancient feature of gut microbial communities and that sharing habitats with humans may have important effects on the structure and function of the primate microbiota
