Abstract

The ideas and techniques of physics have been systematically applied to the study of living matter since the 1950s and 1960s. As a result a rapid and large increase has taken place in the research activity in this field and biophysics and molecular biology have emerged as important areas of study. The consequent enormous growth of literature in the field has created great difficulties in tracking out the significant literature of the subject. To cope with this unprecedented growth of literature, a ranking list of periodicals in this field has been prepared on the basis of citations in the Annual review of biochemistry for 1968,1969, and 1970. This list is expected to reflect the impact of literature on the progress of biochemical knowledge more accurately than the list prepared by Henkle in 1938. The present list brings out the predominant position of biochemical research in the total scientific effort today, and the increasing bias of cognate disciplines towards biochemical methodologies. A method of analysis of the number of citations in relation to size of the journal concerned and average length of the papers published has been developed and applied in this study. The analysis yields three parameters which should be useful in assessing the actual scientific interest of a journal in relation to the number of papers published, compactness of the information content, and the scientific value of the papers in relation to compactness of presentation.

Abstract

The racial and ethnic representation of individuals in the workforce is not comparable to that in the general population. In 2010, African Americans constituted 12.6% of the US population. However, African Americans represented less than 5% of PhD recipients in 2010; African American women comprised less than 1% of the degrees awarded in that same year. These disappointing statistics have sparked conversations regarding the retention of underrepresented groups with a focus on what helps to ensure these individuals will transition through the science, technology, engineering, and mathematics (STEM) pipeline. This chapter provides insight into the elements of the Spelman College learning environment that empower women of African descent to become agents of their success while facilitating their movement through the STEM pipeline. The chapter focuses on interventions and resources developed in the Chemistry and Biochemistry Department to foster student-centered learning. Described herein are cocurricular strategies and course-based interventions are used synergistically to enhance student outcomes. The approach to curricular innovation is framed by theories related to community of inquiry (CoI), metacognition, agency, and self-regulated learning. Strategic institutional investments have underpinned these efforts. In addition to providing a snapshot of student outcomes, the authors discuss lessons learned along with the realities of engaging in this type of intellectual work to elucidate the feasibility of adopting similar strategies at other institutions.

Abstract

Purpose

The purpose of this paper is to explore webometric analysis of keywords and expressions of the biochemistry field of study via LexiURL Searcher.

Design/methodology/approach

Interfaces for assisting users with information access have received considerable attention. Along with the extraction of data on Web sites for webometric purposes (e.g. link analysis, ranking of Web sites, etc.), LexiURL Searcher presents some information on the arrangement of links among different Web sites. Such capability enables users to identify one or more Web sites around their intended subject and, accordingly, explore all Web sites linked with their identified Web site(s). LexiURL Searcher has preceded webometric analysis by considering the main expressions and keywords derived from the MeSH database.

Findings

The worldwide survey indicated that links from countries such as England, Japan, Germany, Australia and Canada were among the Web sites that are most used in biochemistry. Alternatively, other countries such as Singapore, Thailand and Poland had the most advantageous links to the outside world, whereas South Africa, New Zealand and The Netherlands had the least link effect. Biochemistry, being a specialized domain, would benefit greatly from site linking and would provide users the most assistance in information processing.

Originality/value

Most webometric studies remain on the level of link analysis and Web site statuses; however, this paper gives information on the common thread Web sites based on a standard thesaurus.

Abstract

With the introduction of systems of financial management, departmental computers are needed to provide the cost analysis reports from clinical biochemistry and other laboratory departments. To avoid unnecessary duplication of effort, it is important that laboratory data management computers can produce the cost reports required. Any viable system should take account of the additional costs involved in emergency work, the processing of high risk samples etc. Such a system is described, and an indication of the flexibility of the cost analysis software is given. The problems are largely logistical, as the computer searches needed are lengthy, and at present are performed out of normal working hours.

Abstract

Purpose

To understand what differences exist between first year biology and final year biochemistry students in University College Dublin so that measures can be taken to address those needs. It examines student's awareness and use of different sources of information for their course‐work, their use of the (E‐) library, why they visited the university library, the type of assistance they had received in using the library as well as the type of instruction they would like to receive in the future.

Design/methodology/approach

A questionnaire was designed and administered to both sample groups to investigate the information‐seeking behaviour of these students in different years of their studies.

Findings

The study highlights the positive aspects of seeking information from the student's perspective as well as the barriers they encountered when seeking course‐related information. The findings show that there are differences in the extent to which sources of information are used by students in different years of their studies. Apart from web sites and web‐based lecture notes, lack of awareness is the primary reason why undergraduate biology students did not use the library's electronic databases.

Research limitations/implications

The study does not distinguish between third and fourth year students in the final year sample.

Practical implications

One of the key recommendations is that bibliographic instruction should meet the specific information needs of first year biology and final year biochemistry students as well as greater liaison between faculty and librarians in the area of collection development and information literacy.

Originality/value

This paper establishes the importance of a cross‐sectional study in understanding the difference in students' information needs in different years of their studies.

Abstract

Process-oriented guided-inquiry learning (POGIL) is a student-centered instructional strategy to actively engage students in the classroom in promoting content mastery, critical thinking, and process skills. The students organize into groups of three to four, and each group member works collaboratively to construct their understanding as they proceed through the embedded learning cycle in the POGIL activity. Each group member has a specific role and actively engages in the learning process. The roles rotate periodically, and each student has the opportunity to develop essential process skills, such as leadership skills, oral and written communication skills, team-building skills, and information-processing skills. The student groups are self-managed, and the instructor serves as a facilitator of student learning. A POGIL activity typically contains a model that the students deconstruct using a series of guided, exploratory questions. The students develop concepts (concept invention) as the group members reach a valid, consensus conclusion. The students apply their concepts to new problems completing the learning cycle. The authors implemented POGIL instruction in several chemistry courses at Jackson State University and Tuskegee University. They share their initial findings, experiences, and insights gained using a new instructional strategy.

Abstract

Purpose

The purpose of this paper is to discuss the implementation of lean methodology to reduce the turnaround time (TAT) of a clinical laboratory in a super speciality hospital. Delays in report delivery lead to delayed diagnosis increased waiting time and decreased customer satisfaction. The reduction in TAT will lead to increased patient satisfaction, quality of care, employee satisfaction and ultimately the hospital’s revenue.

Design/methodology/approach

The generic causes resulting in increasing TAT of clinical laboratories were identified using lean tools and techniques such as value stream mapping (VSM), Gemba, Pareto Analysis and Root Cause Analysis. VSM was used as a tool to analyze the current state of the process and further VSM was used to design the future state with suggestions for process improvements.

Findings

This study identified 12 major non-value added factors for the hematology laboratory and 5 major non-value added factors for the biochemistry lab which were acting as bottlenecks resulting in limiting throughput. A four-month research study by the authors together with hospital quality department and laboratory staff members led to reduction of the average TAT from 180 to 95minutes in the hematology lab and from 268 to 208 minutes in the biochemistry lab.

Practical implications

Very few improvement initiatives in Indian healthcare are based on industrial engineering tools and techniques, which might be due to a lack of interaction between healthcare and engineering. The study provides a positive outcome in terms of improving the efficiency of services in hospitals and identifies a scope for lean in the Indian healthcare sector.

Social implications

Applying lean in the Indian healthcare sector gives its own potential solution to the problem caused, due to a wide gap between lean accessibility and lean implementation. Lean helped in changing the mindset of an organization toward providing the highest quality of services with faster delivery at an optimal cost.

Originality/value

This paper is an effort to reduce the gap between healthcare and industrial engineering and enhancing the use of lean practices in Indian healthcare. The study is motivated toward implementing lean methodology successfully in services.

Abstract

The important quality characteristics of lean meat are freshness, tenderness, colour, flavour, juiciness and water‐holding capacity (i.e. absence of drip). Lean meat is produced from muscle and the biochemistry of muscle has provided a firm theoretical basis for meat technology. In many instances, some of which will be discussed here, a knowledge of muscle biochemistry has allowed meat technologists to improve meat quality or to avoid its deterioration. Before considering the biochemical basis of meat quality it is necessary to outline some general aspects of the structure and metabolism of muscle.

Abstract

A new N-halamine precursor, 5-methyl-5-aminomethylhydantoin (AH), was synthesized. This N-halamine precursor can be coated onto cotton surfaces with the addition of the crosslinking agent butanetetracarboxylic acid (BTCA) and rendered biocidal by exposure to halogen solutions either before or after curing the coating or material. Standard washing tests show that covalently bound AH/BTCA on the cotton swatches can survive repeated washing cycles. After 50 washing cycles, chlorinated cotton swatches had lost 98.7 % of oxidative Cl+, but after rechlorination, almost 43.5 % of Cl+ was regained. Biocidal tests indicated that the cotton swatches coated with chlorinated AH/BTCA were effective against Gram positive Staphylococcus aureus and Gram negative Escherichia coli.

Abstract

Purpose

The purpose of this study was to examined the health effects of raw and cooked aqueous and methanol extracts of Vigna unguiculata on kidney function in Wistar rats.

Design/methodology/approach

Thirty-six Wistar rats (weighing 160 ± 10 g) were randomly assigned into nine (9) groups (n = 4). Group I (control): no extract. Groups II and III (aqueous extract of the cooked 350 mg/kg and 550 mg/kg). Groups IV and V (methanol extracts of cooked 350 mg/kg and 550 mg/kg). Groups VI and VII (methanol extracts of raw 350 mg/kg and 550 mg/kg). Groups VIII and IX (aqueous extract of raw 350 mg/kg and 550 mg/kg). After the seventh day of the trial, the rats were euthanized with chloroform, and blood samples were collected for biochemical analysis.

Findings

Results showed that the doses applied for cooked and raw V. unguiculata significantly (p < 0.05) enhanced kidney functions by increasing the body weight, glucose level, concentration of serum urea, creatinine, total protein, potassium and chloride in test groups compared with control. The packed cell volume and haemoglobin concentrations of raw aqueous extract at 550 mg/kg (36.5 ± 5.1; 12.3 ± 2.8) were significantly (p = 0.001) higher (29.8 ± 11.8; 10.3 ± 3.9) than the 350 mg/kg dose of the same extract, and cooked aqueous extract at 350 mg/kg dose was significantly (p = 0.001) higher (28.0 ± 10.1; 9.3 ± 3.4) than that of 550 mg/kg (25.8 ± 4.9; 8.8 ± 3.9) dose of the extracts.

Originality/value

The nutritional content of V. unguiculata potentially can augment the nutritional content of a diet and to a large extent, the regular consumers’ health. Essentially, V. unguiculata is composed of both macro and micronutrients capable of promoting normal kidney function.
